Biosynthesis of chlorophyll b and the chlorophyll cycle

Photosynth Res. 2002;74(2):187-93. doi: 10.1023/A:1020959610952.


Recent progress in the knowledge of chlorophyll b biosynthesis from chlorophyllide a and reduction of chlorophyll b to chlorophyll a is described. The minireview includes a description of the enzymes involved in these reactions and, where appropriate, of the genes encoding these enzymes. The possible physiological role of the mutual transformation of chlorophylls a and b (chlorophyll cycle) and the evolution of chlorophyll b formation are discussed.
