Pathway Description
Chlorophyll Cycle
Solanum lycopersicum
Physiological Pathway
Chlorophyll a and chlorophyll b are important light harvesting pigments that capture photons and direct them to reaction centers within the plant. Both chlorophyll a and b have essentially the same structure with the exception of the methyl group on carbon 7 of chlorophyll a and a formyl group on carbon 7 of chlorophyll b. The process by which chlorophyll b is synthesized was only recently elucidated with the discovery of the enzyme chlorophyllide a oxygenase, or CAO, which showed that this enzyme was capable of catalyzing the chemical transition from chlorophyll a to chlorophyll b.
