Biophysicochemical PropertiesKinetic parameters: KM=60 uM for S-adenosyl-L-methionine {ECO:0000269|PubMed:2684666}; pH dependence: Optimum pH is 9.9. {ECO:0000269|PubMed:2684666};
Biophysicochemical PropertiesKinetic parameters: KM=60 uM for S-adenosyl-L-methionine ; pH dependence: Optimum pH is 9.9. ;
Catalytic ActivityS-adenosyl-L-methionine + phosphatidylethanolamine = S-adenosyl-L-homocysteine + phosphatidyl-N-methylethanolamine.
FunctionCatalyzes the first step in the conversion of phosphatidylethanolamine to phosphatidylcholine during the methylation pathway of phosphatidylcholine biosynthesis. Preferentially converts di-C16:1 substrates. {ECO:0000269|PubMed:15258140, ECO:0000269|PubMed:2684666, ECO:0000269|PubMed:2850468, ECO:0000269|PubMed:3025587, ECO:0000269|PubMed:3066687, ECO:0000269|PubMed:6759124, ECO:0000269|PubMed:6988218}.
