Rhodobacter sphaeroides spd mutations allow cytochrome c2-independent photosynthetic growth.

Journal of bacteriology - 1 Apr 1990

Rott M A, Donohue T J

Abstract excerpt

In Rhodobacter sphaeroides, cytochrome c2 (cyt c2) is a periplasmic redox protein required for photosynthetic electron transfer. cyt c2-deficient mutants created by replacing the gene encoding the apoprotein for cyt c2 (cycA) with a kanamycin resistance cartridge are photosynthetically incompetent. Spontaneous mutations that suppress this photosynthesis deficiency (spd mutants) arise at a frequency of 1 to 10 in...
