physiological function | a bacteriochlorophyll-less mutant of Rhodopseudomonas sphaeroides excretes tetrapyrrole-protein complex into the incubation medium. The major pigment of the complex is 2-desacetyl-2-vinylbacteriopheophorbide, indicating the existence of an alternate pathway of bacteriochlorophyll synthesis. This implies that reduction from the chlorin to the tetrahydroporphyrin stage can occur either before or after hydration of the 2-vinyl substituent of chlorophyllide a to an a-hydroxyethyl group. The mutant is presumably deficient in the enzyme responsible for hydration of the 2-vinyl to the 2-alpha-hydroxyethyl group | Cereibacter sphaeroides |
