Webb1 jan. 2024 · Phytyl-PP is the substrate for the synthesis of tocopherol (vitamin E) and phylloquinone (vitamin K1) ( 9, 10 ). Because phytyl-PP derived from phytol phosphorylation is the main source for tocopherol synthesis, the vte5 and vte6 mutants of Arabidopsis are tocopherol deficient. The pathway of phytol degradation in plants is largely unknown. Webb1 jan. 2024 · In the past years, chlorophyll catabolism was identified as the primary source of phytyl diphosphate for tocopherol synthesis by the action of two enzymes, PHYTOL KINASE (VTE5) and PHYTHYL PHOSPHATE KINASE (VTE6) that are able to recycle the chlorophyll-derived phytol. hawaii driver license class 23 https://oursweethome.net
