Protein

Phosphomethylpyrimidine synthase

Gene
thiC, slr0118
Organism
Synechocystis sp. (strain PCC 6803 / Kazusa)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

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 By similarity.UniRule annotation

Catalytic activityi

5-amino-1-(5-phospho-D-ribosyl)imidazole + S-adenosyl-L-methionine = 4-amino-2-methyl-5-phosphomethylpyrimidine + 5'-deoxyadenosine + L-methionine + formate + CO.UniRule annotation

Cofactori

Binds 1 4Fe-4S cluster per subunit. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine By similarity.
