Sysname
S-adenosyl-L-methionine:protein-C-terminal-S-farnesyl-L-cysteine O-methyltransferase
Reaction(IUBMB)
S-adenosyl-L-methionine + protein C-terminal S-farnesyl-L-cysteine = S-adenosyl-L-homocysteine + protein C-terminal S-farnesyl-L-cysteine methyl ester [RN:R04496]
Reaction(KEGG)
Substrate
S-adenosyl-L-methionine [CPD:C00019];
protein C-terminal S-farnesyl-L-cysteine [CPD:C04506]
