Organism
Acidithiobacillus ferrooxidans (strain ATCC 53993) (Leptospirillum ferrooxidans (ATCC 53993))
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the rearrangement of 1-deoxy-D-xylulose 5-phosphate (DXP) to produce the thiazole phosphate moiety of thiamine. Sulfur is provided by the thiocarboxylate moiety of the carrier protein ThiS. In vitro, sulfur can be provided by H2S.UniRule annotation

Catalytic activityi

1-deoxy-D-xylulose 5-phosphate + 2-iminoacetate + thiocarboxy-adenylate-[sulfur-carrier protein ThiS] = 2-((2R,5Z)-2-carboxy-4-methylthiazol-5(2H)-ylidene)ethyl phosphate + [sulfur-carrier protein ThiS] + 2 H2O.UniRule annotation

Pathwayi: thiamine diphosphate biosynthesis

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.
