Maintaining Methylation Activities during Salt Stress. The Involvement of Adenosine Kinase1
Abstract
Synthesis of the compatible osmolyte Gly betaine is increased in salt-stressed spinach (Spinacia oleracea). Gly betaine arises by oxidation of choline from phosphocholine. Phosphocholine is synthesized in the cytosol by three successive S-adenosyl-Met-dependent N-methylations of phosphoethanolamine. With each transmethylation, a molecule of S-adenosylhomo-Cys (SAH) is produced, a potent inhibitor of S-adenosyl-Met-dependent methyltransferases. …
