MetabolomicsMapping the biosynthetic pathway of a hybrid polyketide-nonribosomal peptide in a metazoan
Polyketide synthase (PKS) and nonribosomal peptide synthetase (NRPS) hybrid systems typically use complex protein-protein interactions to facilitate direct transfer of intermediates between these multimodular megaenzymes. In the canal-associated neurons (CANs) of Caenorhabditis elegans, PKS-1 and NR...

MetabolomicsBiosynthesis of Isonitrile Lipopeptides by Conserved Non-ribosomal Peptide Synthetase Gene Clusters in Actinobacteria
A putative lipopeptide biosynthetic gene cluster is conserved in many species of Actinobacteria, including Mycobacterium tuberculosis and Mycobacterium marinum, but the specific function of the encoding proteins has been elusive. Using both in vivo heterologous reconstitution and in vitro biochemica...

TranscriptomicsTranscriptomic responses in Arabidopsis thaliana to PIPL3 peptide treatment
In order to investigate possible roles of IDL and PIP/PIPL peptides, the transcriptomic response of Arabidopsis seedlings to treatment with PIPL3 peptide was analysed. PIPL3 (At4g37295) was chosen, as no functional data was available for this peptide; furthermore, PIPL3 was expressed in leaf tissue ...

ProteomicsStadard peptide mixture plus HeLa
To test our peak detection and label-free quantitation algorithm, practical applications of AB3D for LC-MS data sets were evaluated using a standard peptide mixture consisting of bovine serum albumin (BSA) peptides with different concentrations, peptides derived from four standard proteins (data ...

TranscriptomicsPeptide alarmone signalling triggers an auto-active bacteriocin necessary for genetic competence
The induction of genetic competence is a strategy used by bacteria to increase their genetic repertoire under stressful environmental conditions. Recently, Streptococcus pneumoniae has been shown to co-ordinate the uptake of transforming DNA with fratricide via increased expression of the peptide ph...

TranscriptomicsThe IDA-LIKE peptides IDL6 and IDL7 are negative modulators of stress responses in Arabidopsis thaliana
We present a functional characterisation of two members of the IDA-LIKE (IDL) peptide family in Arabidopsis thaliana, IDL6 and IDL7. They are processed both C- and N-terminally to produce active peptides. Structure analyses of synthesized IDL6 and IDL7 peptides indicate that they lack secondary stru...

ProteomicsAn environmentally relevant mixture of organophosphate esters induces cholesterol biosynthesis in THP-1 macrophages
Organophosphate esters (OPEs), widely used as flame retardants and plasticizers, are environmental toxicants known to disrupt lipid metabolism. Although most studies have focused on individual OPEs, environmental exposures typically involve complex mixtures. Our previous studies demonstrated that a ...

ProteomicsProteomic profiling by array of tyrosine kinase activity in metastatic malignant melanoma from human tissue specimens
Tyrosine kinase activity profiling of metatstatic malignant melanoma and normal skin tissue samples was performed using peptide kinase arrays. All samples were run in triplicates with and withouth inhbitor PLX4032 and Sutent Malate in order to identify how tyrosine kinases responds to kinase inhibit...
