Chlorophyll pathway

WebThe last steps of chlorophylls (Chls) a and b biosynthesis comprise the formation of chlorophyllide (Chlide) a from protochlorophyllide (PChlide) a, the oxygenation of Chlide a to Chlide b, the esterification of Chlides to the corresponding Chls, and the reduction of b -type pigments to a -type pigments. WebThe intracellular localization of the catabolic pathway is particularly important in the regulation of chlorophyll breakdown. None of the genes encoding the related catabolic enzymes has so far been isolated, which makes chlorophyll degradation an area of opportunity for future research.
