Protein
Uroporphyrinogen-III C-methyltransferase
Gene
cobA, sll0378
Organism
Synechocystis sp. (strain PCC 6803 / Kazusa)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Catalyzes both methylations at C-2 and C-7 of uroporphyrinogen III leading to precorrin-1 and precorrin-2; their oxidative esterification gives respectively factor I octamethyl ester and sirohydrochlorin By similarity.

Catalytic activityi

S-adenosyl-L-methionine + uroporphyrinogen III = S-adenosyl-L-homocysteine + precorrin-1.
S-adenosyl-L-methionine + precorrin-1 = S-adenosyl-L-homocysteine + precorrin-2.
