Thiamine biosynthesis protein ThiS; With ThiF, ThiG, and ThiO catalyzes the formation of the thiazole moiety of thiamine pyrophosphate; Derived by automated computational analysis using gene prediction method: Protein Homology.

Thiamine-phosphate pyrophosphorylase; Condenses 4-methyl-5-(beta-hydroxyethyl)thiazole monophosphate (THZ-P) and 2-methyl-4-amino-5-hydroxymethyl pyrimidine pyrophosphate (HMP-PP) to form thiamine monophosphate (TMP). Belongs to the thiamine-phosphate synthase family.

Molybdopterin biosynthesis-like protein MoeZ; The proteins in this cluster have high sequence similarity to MoeB and are possibly involved in the synthesis of molybdopterin, but there has been no biochemical or physiological characterization. There is also no genetic linkage to other molybdopterin cofactor synthesis proteins. These proteins are similar to a Pseudomonas stutzeri protein which is essential to pyridine-2,6-bis(thiocarboxylic acid) synthesis that possibly activates a substrate by adenylation; Derived by automated computational analysis using gene prediction method: Protein [...]

1-deoxy-D-xylulose-5-phosphate synthase; Catalyzes the acyloin condensation reaction between C atoms 2 and 3 of pyruvate and glyceraldehyde 3-phosphate to yield 1-deoxy-D- xylulose-5-phosphate (DXP); Belongs to the transketolase family. DXPS subfamily.

Phosphomethylpyrimidine kinase; Derived by automated computational analysis using gene prediction method: Protein Homology.

FO synthase; 7,8-didemethyl-8-hydroxy-5-deazariboflavin synthase; catalyzes radical-mediated transfer of hydroxybenzyl group from 4-hydroxyphenylpyruvate (HPP) to 5-amino-6-ribitylamino-2,4(1H,3H)-pyrimidinedione to form 7,8-didemethyl-8-hydroxy-5-deazariboflavin (FO); functions in F420 biosynthesis; Derived by automated computational analysis using gene prediction method: Protein Homology.

Thiamine biosynthesis protein ThiI; Catalyzes the ATP-dependent transfer of a sulfur to tRNA to produce 4-thiouridine in position 8 of tRNAs, which functions as a near-UV photosensor. Also catalyzes the transfer of sulfur to the sulfur carrier protein ThiS, forming ThiS-thiocarboxylate. This is a step in the synthesis of thiazole, in the thiamine biosynthesis pathway. The sulfur is donated as persulfide by IscS.

Phosphomethylpyrimidine synthase; Catalyzes the synthesis of the hydroxymethylpyrimidine phosphate (HMP-P) moiety of thiamine from aminoimidazole ribotide (AIR) in a radical S-adenosyl-L-methionine (SAM)-dependent reaction. Belongs to the ThiC family.
