ENZYME entry: EC 2.1.1.329

Accepted Name
Demethylphylloquinol methyltransferase.
Alternative Name(s)
2-phytyl-1,4-naphthoquinol methyltransferase.
Reaction catalysed
S-adenosyl-L-methionine + demethylphylloquinol <=> S-adenosyl-L-homocysteine + phylloquinol
Comment(s)
  • The enzyme, found in plants and cyanobacteria, catalyzes the final step in the biosynthesis of phylloquinone (vitamin K(1)), an electron carrier associated with photosystem I.
  • The enzyme is specific for the quinol form of the substrate, and does not act on the quinone form.
  • Formerly EC 2.1.1.n12.
