2.1.1.100 |
Accepted name: |
protein-S-isoprenylcysteine O-methyltransferase |
Reaction: |
S-adenosyl-L-methionine + protein C-terminal S-farnesyl-L-cysteine = S-adenosyl-L-homocysteine + protein C-terminal S-farnesyl-L-cysteine methyl ester |
Other name(s): |
farnesyl cysteine C-terminal methyltransferase; farnesyl-protein carboxymethyltransferase; protein C-terminal farnesylcysteine O-methyltransferase; farnesylated protein C-terminal O-methyltransferase; isoprenylated protein methyltransferase; prenylated protein methyltransferase; protein S-farnesylcysteine C-terminal methyltransferase; S-farnesylcysteine methyltransferase; prenylcysteine carboxylmethyltransferase [misleading]; prenylcysteine carboxymethyltransferase [misleading]; prenylcysteine methyltransferase |
Systematic name: |
S-adenosyl-L-methionine:protein-C-terminal-S-farnesyl-L-cysteine O-methyltransferase |
Comments: |
C-terminal S-geranylgeranylcysteine and S-geranylcysteine residues are also methylated, but more slowly. |
