Protein Information
Name MOCS3 {ECO:0000255|HAMAP-Rule:MF_03049}
Function Plays a central role in 2-thiolation of mcm(5)S(2)U at tRNA wobble positions of cytosolic tRNA(Lys), tRNA(Glu) and tRNA(Gln). Also essential during biosynthesis of the molybdenum cofactor. Acts by mediating the C-terminal thiocarboxylation of sulfur carriers URM1 and MOCS2A. Its N-terminus first activates URM1 and MOCS2A as acyl- adenylates (-COAMP), then the persulfide sulfur on the catalytic cysteine is transferred to URM1 and MOCS2A to form thiocarboxylation (- COSH) of their C-terminus. The reaction probably involves hydrogen sulfide that is generated from the persulfide intermediate and that acts as nucleophile towards URM1 and MOCS2A. Subsequently, a transient disulfide bond is formed. Does not use thiosulfate as sulfur donor; NFS1 probably acting as a sulfur donor for thiocarboxylation reactions.
Cellular Location Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03049, ECO:0000269|PubMed:15073332}

Molybdenum cofactor (MoCo) is necessary for the functionof all molybdoenzymes. One of the enzymes required for thebiosynthesis of MoCo is molybdopterin synthase (MPT synthase). Theprotein encoded by this gene adenylates and activates MPT synthase.This gene contains no introns. A pseudogene of this gene is presenton chromosome 14.
