Summary:
General Background

Phylloquinone (vitamin K1, 2-methyl-3-phytyl-1,4-naphthoquinone) acts as the electron transfer cofactor A1 of photosystem I (PS I) in higher plants and cyanobacteria. In non-photosynthetic microbes the very similar compound a menaquinone plays an essential role in several anaerobic electron transport systems [Sharma96]. The chemical structure of menaquinone (vitamin K2) exhibits a partly unsaturated side chain consisting most often 7 prenyl units, whereas phylloquinone consists of a mostly saturated phytyl side chain of 4 units [Shimada05a].

The biosynthesis of phylloquinone was studied in detail in the cyanobacterium Synechocystis sp. PCC 6803 and the genes encoding enzymes of this pathway were identified by comparison with genes encoding enzymes of the menaquinone biosynthetic pathway in Escherichia coli (see menaquinol-8 biosynthesis) [Sharma96]. With the isolation and functional confirmation of the homolog genes in Synechocystis encoding for 1,4-dihydroxy-2-naphthoate phytyltransferase, naphthoyl-CoA synthase [Johnson00a], 2-phytyl-1,4-naphthoquinone methyltransferase [Sakuragi02], 2-succinyl-5-enolpyruvyl-6-hydroxy-3-cyclohexene-1-carboxylate synthase and O-succinylbenzoate synthase [Johnson03], most of the enzymatic steps of the phylloquinone bisoynthesis have been determined and proven to be highly identical with those in the menaquinone biosynthesis.

The biosynthesis of certain components of the multienzyme complex PS I (such as phylloquinone) in cyanobacteria and plants have been found to follow analogous routes, including corresponding enzymatic activities [Heide82a] [Kolkmann87, Simantiras89, Simantiras91], reflecting the phylogenetic origin of PS I in photosynthetic microbes.

About This Pathway

The enzymatic steps involved in the biosynthesis of phylloquinone in cyanobacteria and plants are almost identical to the biosynthetic route leading to the microbial complement menaquinone. The discernible step between phylloquinone and menaquinone biosynthesis is the prenylation of 1,4-dihydroxy-2-naphthoate (DHNA). The DHNA phytyltransferase catalyzes the attachment of a C-20 phytyl side chain leading to demethylphylloquinone [Shimada05a], whereas microbial DHNA prenyltransferases attache a multiprenyl side chain, forming demethylmenaquinones. The length of the side chain varies among different species.

It has been found that phylloquinone is not absolutely required for efficient electron transfer in PS I [Johnson00a]. At least in Synechocystis sp. PCC 6803, benzoquinones such as plastoquinone-9, which usually act as secondary electron acceptors in PS II [Johnson01a, Sakuragi05], can efficiently replace phylloquinone in the A1-site of PS I as a one-electron cofactor. However, as shown in both Arabidopsis and Synechocystis sp. PCC 6803 mutants, the deficiency of phylloquinone causes distortions in the thylakoid structure of chloroplasts, decreases the content of PS I, and affects the functionality of PS II [Shimada05a].
