Phosphocholine synthesis in spinach: Characterization of phosphoethanolamine N‐methyltransferase
Abstract
Phosphocholine is a precursor for phosphatidylcholine or it may be hydrolysed to choline. Choline can be oxidized to form the compatible osmolyte glycine betaine which is accumulated by many plants under conditions of osmotic stress. In Spinacia oleracea phosphocholine is synthesized by 3 sequential N ‐methylations of phosphoethanolamine with the first step catalysed by the enzyme phosphoethanolamine N ‐methyltransferase (EC 2.1.1.103). This …
