General annotation (Comments)

Function

Converts Mg-protoporphyrin IX to Mg-protoporphyrin IX methylester using S-adenosyl-L-methionine as a cofactor.

Catalytic activity

S-adenosyl-L-methionine + magnesium protoporphyrin IX = S-adenosyl-L-homocysteine + magnesium protoporphyrin IX 13-methyl ester.

Pathway

Porphyrin-containing compound metabolism; chlorophyll biosynthesis (light-independent).

Sequence similarities

Belongs to the class I-like SAM-binding methyltransferase superfamily. Magnesium protoporphyrin O-methyltransferase family.
