The mutant E/sub 1/ of Anacystis nidulans R/sub 2/ requires high CO/sub 2/ concentration for growth but was able to adapt to low CO/sub 2/ concentration. This was exhibited by the increased ability to accumulate inorganic carbon within the cells and the large increase in the amount of a 42-kilodalton polypeptide located in the cytoplasmic membrane. The adaptation occurred in E/sub 1/ cells at an extracellular CO/sub 2/ concentration as high as 0.3%, which was 8 times the concentration for maximal adaptation in R/sub 2/ cells. The ability of E/sub 1/ cells to exhibit low CO/sub 2/ characteristics at a higher CO/sub 2/ concentration was attributed to lower intracellular CO/sub 2/ concentration.
