Protein

Uroporphyrinogen-III C-methyltransferase

Gene

nirE

Organism
Paracoccus denitrificans (strain Pd 1222)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes the methylation of both 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). Inactivation of uroporphyrinogen-III methyltransferase results in the loss of nitrite and nitric oxide reductase activities, but not of nitrous oxide reductase activity. Likely involved in heme D1 biosynthesis.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.

Pathway:isiroheme biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes precorrin-2 from uroporphyrinogen III.
Proteins known to be involved in this subpathway in this organism are:
  1. Uroporphyrinogen-III C-methyltransferase (nirE)
This subpathway is part of the pathway siroheme biosynthesis, which is itself part of Porphyrin-containing compound metabolism.
