General annotation (Comments)

Function

Involved in the heme biosynthesis. Catalyzes the aerobic oxidative decarboxylation of propionate groups of rings A and B of coproporphyrinogen-III to yield the vinyl groups in protoporphyrinogen-IX By similarity. HAMAP-Rule MF_00333

Catalytic activity

Coproporphyrinogen-III + O2 + 2 H+ = protoporphyrinogen-IX + 2 CO2 + 2 H2O. HAMAP-Rule MF_00333

Cofactor

Divalent cations By similarity. HAMAP-Rule MF_00333

Pathway

Porphyrin-containing compound metabolism; protoporphyrin-IX biosynthesis; protoporphyrinogen-IX from coproporphyrinogen-III (O2 route): step 1/1. HAMAP-Rule MF_00333

Subunit structure

Homodimer By similarity. HAMAP-Rule MF_00333

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00333.

Sequence similarities

Belongs to the aerobic coproporphyrinogen-III oxidase family.
