Abstract

Phylloquinol (the quinol form of vitamin K1) is synthesized from 2-phytyl-1,4-naphthoquinol and S-adenosylmethionine at the thylakoid membranes of spinach chloroplasts. The addition of soluble stroma protein (chloroplast extract) is necessary S-Adenosylhomocysteine acts as strong competitive inhibitor.
