Acts as a sulfur carrier required for 2-thiolation of mcm(5)S(2)U at tRNA wobble positions of tRNA(Lys), tRNA(Glu) and tRNA(Gln). Serves as sulfur donor in tRNA 2-thiolation reaction by thiocarboxylated (-COSH) at its C-terminus by MOCS3. The sulfur is then transferred to tRNA to form 2-thiolation of mcm(5)S(2)U. May also act as an ubiquitin-like protein that is covalently conjugated to other proteins; the relevance of such function is however unclear in vivo. Capra hircus (taxid: 9925)

Urm1 (Ubiquitin-Related Modifier1) The Urm1 fold, like those of two closely related proteins MoaD (molybdopterin synthase) and ThiS (sulfur carrier protein), is similar to that of ubiquitin although there is little or no sequence similarity. The C-terminal glycines of Urm1 are conjugated to an E1-like protein Uba4 as part of a novel conjugation system in yeast. The Urm1 fold is found only in eukaryotes. Length = 94

MoaD family. Members of this family are involved in biosynthesis of the molybdenum cofactor (Moco), an essential cofactor of a diverse group of redox enzymes. Moco biosynthesis is an evolutionarily conserved pathway present in eubacteria, archaea and eukaryotes. Moco contains a tricyclic pyranopterin, termed molybdopterin (MPT), that contains the cis-dithiolene group responsible for molybdenum ligation. This dithiolene group is generated by MPT synthase, the second major step in Moco biosynthesis. MPT synthase consists of a large (MoeE) and small (MoaD) subunit. The small subunit is inserted into the lare subunit to form the active site. The small subunit, which is structurally similar to ubiquitin, contains a C-terminal thiocarboxylated glycine residue that serves as a sulfur donor for the synthesis of the MPT dithiolene group.
Members of this family appear to be archaeal versions of MoaD, subunit 1 of molybdopterin converting factor. This model has been split from the bacterial/eukaryotic equivalog model TIGR01682 because the presence of two members of this family in a substantial number of archaeal species suggests that roles might not be interchangeable.
