CC -!- FUNCTION: Catalyzes the post-translational methylation of isoprenylated
CC C-terminal cysteine residues. Carboxyl methylation is a reversible and
CC potentially regulated step in the post-translational modification of
CC prenylated proteins (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[protein]-C-terminal S-[(2E,6E)-farnesyl]-L-cysteine + S-
CC adenosyl-L-methionine = [protein]-C-terminal S-[(2E,6E)-farnesyl]-L-
CC cysteine methyl ester + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:21672, Rhea:RHEA-COMP:12125, Rhea:RHEA-COMP:12126,
CC ChEBI:CHEBI:57856, ChEBI:CHEBI:59789, ChEBI:CHEBI:90510,
CC ChEBI:CHEBI:90511; EC=2.1.1.100;
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC Note=Divalent metal cations. Probably Zn(2+). {ECO:0000250};
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000250};
CC Multi-pass membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the class VI-like SAM-binding methyltransferase
CC superfamily. Isoprenylcysteine carboxyl methyltransferase family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAF15691.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
