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. WebMar 30, 2024 · Chlorophyll is the most important carrier of photosynthesis in plants and is therefore vital for plant growth and development. Synthesis of 5-aminolevulinic acid (ALA) is initiated and catalyzed by glutamyl-tRNA reductase (GluTR) and is the rate-limiting step in chlorophyll biosynthesis. GluTR is controlled by several regulating factors. ceh znacenje
