Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

Catalyzes the conversion of precorrin-2 into siroheme. This reaction consist of the NAD-dependent oxidation of precorrin-2 into sirohydrochlorin and its subsequent ferrochelation into siroheme. Ref.4

Catalytic activity

Precorrin-2 + NAD+ = sirohydrochlorin + NADH.

Siroheme + 2 H+ = sirohydrochlorin + Fe2+.

Pathway

Porphyrin metabolism; siroheme biosynthesis; siroheme from sirohydrochlorin: step 1/1.

Porphyrin metabolism; siroheme biosynthesis; sirohydrochlorin from precorrin-2: step 1/1.

Subunit structure

Homodimer. Ref.5

Sequence similarities

Belongs to the MET8 family.
