Methods for selective covalent modification of amino acids on proteins can enable a diverse array of applications, spanning probes and modulators of protein function to proteomics<sup>1-3</sup>. Owing to their high nucleophilicity, cysteine and lysine residues are the most common points of attachment for protein bioconjugation chemistry through acid-base reactivity<sup>3,4</sup>. Here we report a redox-based strategy for bioconjugation of tryptophan, the rarest amino acid, using oxaziridine reag ...[more]

Triazolinedione protein modification: from an overlooked off-target effect to a tryptophan-based bioconjugation strategy

Project description:Labelling of tyrosine residues in peptides and proteins has been reported to selectively occur via a 'tyrosine-click' reaction with triazolinedione reagents (TAD). However, we here demonstrate that TAD reagents are actually not selective for tyrosine and that tryptophan residues are in fact also labelled with these reagents. This off-target labelling remained under the radar as it is challenging to detect these physiologically stable but thermally labile modifications with the commonly used HCD and CID MS/MS techniques. We show that selectivity of tryptophan over tyrosine can be achieved by lowering the pH of the aqueous buffer to effect selective Trp-labelling. Given the low relative abundance of tryptophan compared to tyrosine in natural proteins, this results in a new site-selective bioconjugation method that does not rely on enzymes nor unnatural amino acids and is demonstrated for peptides and recombinant proteins.

Post-epidemic eosinophilia myalgia syndrome associated with L-Tryptophan

Project description:Eosinophilia–myalgia syndrome (EMS) is characterized by subacute onset of myalgias and peripheral eosinophilia, followed by chronic neuropathy and skin induration. The EMS epidemic in 1989 was linked to L-tryptophan consumption originating from a single source. Following the Food and Drug Administration (FDA) ban on the sale of L-tryptophan, the incidence of EMS declined rapidly. Moreover, no new cases have been published since the FDA ban was lifted in 2005. We report the clinical, histopathological and immunogenetic features of a new case of L-tryptophan-associated EMS along with evidence of activated transforming growth factor-ß and interleukin-4 signaling in the lesional skin. 6 samples were analyzed to include EMS patient and two replicates along with three normal controls

Single electron transfer between sulfonium and tryptophan enables site-selective photo crosslinking of methyllysine reader proteins

Project description:Reader proteins play significant roles in cell signaling from site-specific lysine methylation, but progress of new reader investigations is rather slow. Photoreactive crosslinkers enable the discovery of reader proteins, but the chemical synthesis required to optimize the placement of the photoreactive group is laborious. In addition, active intermediates such as nitrene and carbene may cause significant non-specific crosslinking. Here we report dimethylsulfonium as a methyllysine mimic that binds to specific readers and can subsequently crosslink to a conserved tryptophan inside the binding pocket through single electron transfer under UV irradiation. The crosslinking requires σ-π electron-donor-acceptor interaction between sulfonium and indole as a key step, facilitating excellent tryptophan site-selectivity and orthogonality to distinct methyllysine readers. Moreover, excited tryptophan without proximate sulfonium leads to minimal non-specific crosslinking from relaxation. This method could escalate the discovery of methyllysine readers from complex cell samples. Furthermore, this photo crosslinking concept could also be expanded to develop more types of microenvironment-dependent conjugations to site-specific tryptophan.

Tryptophan metabolism response in E. coli

Project description:DNA microarray analysis of gene expression in response to physiological and genetic changes that affect tryptophan metabolism in Escherichia coli. We investigated the global changes in mRNA abundance in Escherichia coli elicited by various perturbations of tryptophan metabolism. To do so we printed DNA microarrays containing 95% of all annotated E. coli ORFs. We determined the expression profile that is predominantly dictated by the activity of the tryptophan repressor. Only three operons, trp, mtr, and aroH, exhibited appreciable expression changes consistent with this profile. The quantitative changes we observed in mRNA levels for the five genes of the trp operon were consistent within a factor of 2, with expectations based on established Trp protein levels. Several operons known to be regulated by the TyrR protein, aroF-tyrA, aroL, aroP, and aroG, were down-regulated on addition of tryptophan. TyrR can be activated by any one of the three aromatic amino acids. Only one operon, tnaAB, was significantly activated by the presence of tryptophan in the medium. We uncovered a plethora of likely indirect effects of changes in tryptophan metabolism on intracellular mRNA pools, most prominent of which was the sensitivity of arginine biosynthetic operons to tryptophan starvation.

Dietary tryptophan and circadian rhythms

Project description:Mice were fed a normal chow diet or a tryptophan depleted diet for two weeks under normal 12-hr light/dark cycles (LD) or in constant darkness (DD). Mice were sacrificed every 4th hour over the 24-hr circadian cycle. The suprachiasmatic nucleus (SCN) was harvested and RNA was isolated using a standard TRIZOL protocol. The data suggest that dietary tryptophan is an important component of the diet regulating circadian homeostsis.

Tryptophan plays a central role in yeast’s tolerance to isobutanol

Project description:Isobutanol is considered a potential biofuel and can be produced by genetically modified microorganisms. Saccharomyces cerevisiae inherently produces isobutanol through valine intermediate(s), so it serves as a good host. However, isobutanol's toxicity remains a key obstacle for bioproduction. In our study, we first used image recognition to screen the colony growth of a yeast gene deletion library and inferred that genes involved in tryptophan biosynthesis, ubiquitination, and the pentose phosphate pathway (PPP) contribute to isobutanol tolerance. The importance of tryptophan in yeast's tolerance to isobutanol was confirmed by the recovery of isobutanol tolerance in a tryptophan biosynthesis defective strain by adding exogenous tryptophan. Transcriptomic analysis revealed that amino acid biosynthesis- and transportation-related genes in a tryptophan biosynthesis defective host were up regulated under conditions such as nitrogen starvation. This may explain why ubiquitination for protein degradation was involved for the protein turnover. PPP metabolites and vitamin B1/B6 may serve as precursors and cofactors in tryptophan biosynthesis to enhance isobutanol tolerance. Furthermore, the tolerance mechanism may also be linked to tryptophan metabolism, including the kynurenine pathway and nicotinamide adenine dinucleotide biosynthesis. Both pathways are responsible for cellular redox balance and antioxidative ability and figured out that tryptophan may play a crucial role on isobutanol tolerance. Our study highlights the central role of tryptophan in yeast's isobutanol tolerance and offers new clues for engineering a yeast host with strong isobutanol tolerance.

SIRT6 regulates Tryptophan catabolism preventing metabolite imbalance and neurodegeneration

Project description:In the brain, tryptophan byproducts are involved in the biosynthesis of proteins, energy-rich molecules (e.g., NAD+), and neurotransmitters (serotonin and melatonin). Impaired tryptophan catabolism, seen in aging, neurodegeneration and psychiatric diseases affects mood, learning, and sleep; however, the reasons for those impairments in elder and these ailments remain unknown. Our results from cellular, Drosophila melanogaster, and mouse models indicate that SIRT6 regulates tryptophan catabolism by balancing its usage. Mechanistically, SIRT6 regulates tryptophan and sleep quality through changes in gene expression of key genes (e.g., TDO2, AANAT), which results in elevated concentration of neurotoxic metabolites from the kynurenic pathway at the expense of serotonin and melatonin production. Such neurotoxic metabolites can affect various processes in the brain. However, by redirecting tryptophan through TDO2 inhibition in our new SIRT6-KO Drosophila model, the impairments in neuromotor behavior and vacuolar formation a parameters of neurodegeneration could be significantly reversed.
