Webb29 okt. 2024 · Background: Phytyl residues are the common side chains of chlorophyll (Chl) and tocopherols. Geranylgeranyl reductase (GGR), which is encoded by CHLP gene, … WebbThe 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.
