Comments
Comment typeDescription
Alternative ProductsEvent=Alternative splicing; Named isoforms=2; Name=1; IsoId=Q3ED65-1; Sequence=Displayed; Name=2; IsoId=Q3ED65-2; Sequence=VSP_040914;
Catalytic ActivityS-adenosyl-L-methionine + demethylphylloquinone = S-adenosyl-L-homocysteine + phylloquinone. {ECO:0000269|PubMed:17082184}.
Disruption PhenotypeLack of phylloquinone and reduced growth under normal light. Loss of anthocyanin accumulation under high light. {ECO:0000269|PubMed:17082184}.
FunctionInvolved in the biosynthesis of phylloquinone (vitamin K1). Methyltransferase required for the conversion of 2-phytyl- 1,4-beta-naphthoquinone to phylloquinone. {ECO:0000269|PubMed:17082184}.
