Abstract
Chlamydomonas utilizes the cyclic tetrapyrroles chlorophyll, heme, siroheme, vitamin B12, and linear tetrapyrrole (bilin) metabolites as cofactors for photosynthetic light harvesting, electron transport, redox reactions, mitigating oxidative stress, and signaling. With the exception of vitamin B12, Chlamydomonas can synthesize and degrade all of these tetrapyrroles. In this chapter, we review what is currently known about how Chlamydomonas biosynthesizes and metabolizes tetrapyrroles, how these processes are regulated, and the various functions of tetrapyrroles in Chlamydomonas.
