Gene

SPBC21D10.11c

Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the removal of elemental sulfur from cysteine to produce alanine. It supplies the inorganic sulfur for iron-sulfur (Fe-S) clusters. Plays a role in both tRNA-processing and mitochondrial metabolism. Involved in the 2-thio-modification of both 5-carboxymethylaminomethyl-2-thiouridine in mitochondrial tRNAs and 5-methoxycarbonylmethyl-2-thiouridine (mcm5s2U) in cytoplasmic tRNAs.By similarity

Catalytic activityi

L-cysteine + acceptor = L-alanine + S-sulfanyl-acceptor.By similarity

Cofactori

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
