Web14096Phosphoethanolamine N-Methyltransferase from Spinach with activated charcoal and centrifuging (29), and14C incorporation into free base products was measured by counting a sample of the supernatant. TLC tests confirmed that the charcoal did not bind free bases. For assay blanks, EA was omitted. WebPhosphoethanolamine methyltransferases (PMTs) are responsible for the S - adenosylmethionine (SAM)-dependent conversion of pEA to phosphomonomethylethanolamine (pMME), phosphodimethylethanolamine (pDME), and finally pCho. These enzymes have been grouped into three distinct classes ( Fig. 1 ).
