Respiratory electron transport complexes are organized as individual entities or combined as large supercomplexes (SC). Gram-negative bacteria deploy a mitochondrial-like cytochrome (cyt) bc1 (Complex III, CIII2), and may have specific cbb3-type cyt c oxidases (Complex IV, CIV) instead of the canonical aa3-type CIV. Electron transfer between these complexes is mediated by soluble (c2) and membrane-anchored (cy) cyts. Here, we repo ...[more]

Phomopsis amygdala fusicoccadiene synthase

Project description:Fusicoccadiene synthase from Phomopsis amygdali (PaFS) catalyzes the first committed step in the biosynthesis of Fusicoccin A, a diterpene glycoside and a a potential therapeutic agent. PaFS contains a C-terminal prenyltransferase domain that generates geranylgeranyl diphosphate (GGPP) and an N-terminal cyclase domain that utilizes GGPP to generate fusicoccadiene, which comprises the complex 5-8-5 tricyclic hydrocarbon skeleton of Fusicoccin A. The C-termimal domain octamerizes to form a central core, with the eight cyclase domains radiating outward via flexible linker segments with variable extended conformations. Crosslinking-mass spectrometry (XL-MS) experiments affirm and reveal inter-domain interactions, showing that compact conformations can be achieved. These studies, complemented by cryo-EM and functional studies, provide a framework for understanding substrate channeling between consecutive catalytic domains.

VCF1 is a p97/VCP cofactor promoting recognition of ubiquitylated p97-UFD1-NPL4 substrates

Project description:The hexameric AAA+ ATPase p97/VCP functions as an essential mediator of ubiquitin-dependent cellular processes, extracting ubiquitylated proteins from macromolecular complexes or membranes by catalyzing their unfolding. p97 is directed to ubiquitylated client proteins via multiple cofactors, most of which interact with the p97 N-domain. Here, we discover that FAM104A, a protein of unknown function also named VCF1 (VCP/p97 nuclear Cofactor Family member 1), acts as a novel p97 cofactor in human cells. Detailed structure-function studies reveal that VCF1 directly binds p97 via a conserved novel -helical motif that recognizes the p97 N-domain with unusually high affinity, exceeding that of other cofactors. We show that VCF1 engages in joint p97 complex formation with the heterodimeric primary p97 cofactor UFD1-NPL4 and promotes p97-UFD1-NPL4-dependent proteasomal degradation of ubiquitylated substrates in cells. Mechanistically, VCF1 indirectly stimulates UFD1-NPL4 interactions with ubiquitin conjugates via its binding to p97 but has no intrinsic affinity for ubiquitin. Collectively, our findings establish VCF1 as an unconventional p97 cofactor that promotes p97-dependent protein turnover by facilitating p97-UFD1-NPL4 recruitment to ubiquitylated targets.

HPLC-TIMS-TOF-MS of purified mitochondrial I+III2 supercomplex from Arabidopsis thaliana

Project description:Mitochondrial I+III2 supercomplex was purified from Arabidopsis thaliana cells using differential centrifugation including Percoll step gradients and continuous sucrose gradients. Supercomplex fractions were digested with trypsin using the SP3 approach. Peptides were further purified with SepPak cartridges and measured by HPLC-ESI-TIMS-TOF-MS. Database search was performed with MaxQuant (Version 2.0.3.0.) Over 1,300 proteins were identified using this highly sensitive approach, including all known subunits of the I+III2 supercomplex. This MS analysis is part of a publication on the structure of the I+III2 supercomplex from Arabidopsis by Klusch et al., 2022.

Atomic structures of respiratory complex III2 complex IV and supercomplex III2-IV from vascular plants

Project description:Mitochondrial complex III (CIII2) and complex IV (CIV) which can associate into a higher-order supercomplex (SC III2 IV) play key roles in respiration. However, structures of these plant complexes remain unknown. We present atomic models of CIII2, CIV and SC III2 IV from Vigna radiata determined by single-particle cryoEM. The structures reveal plant-specific differences in the MPP domain of CIII2 and define the subunit composition of CIV. Conformational heterogeneity analysis of CIII2 revealed long-range, coordinated movements across the complex as well as the motion of CIII2s iron-sulfur head domain. The CIV structure suggests that, in plants, proton translocation does not occur via the H-channel. The supercomplex interface differs significantly from that in yeast and bacteria in its interacting subunits angle of approach and limited interactions in the mitochondrial matrix. These structures challenge long-standing assumptions about the plant complexes, generate new mechanistic hypotheses and allow for the generation of more selective agricultural inhibitors.

A synthetic crosslinked peptide library for benchmarking crosslinking mass spectrometry search engines

Project description:We have created a synthetic crosslinked peptide library to benchmark crosslinking mass spectrometry search engines. The unique benefit of the library is knowing which identified crosslinks are true and which are false. The data collected from mass spectrometry measurements of the peptide library were used to assess the most frequently used search algorithms. The datasets included will provide an important resource for the crosslinking community to evaluate and optimise search engines, results from which have far-reaching implications.
