Abstract excerpt
Two Escherichia coli mutants that lack both cytochrome o and d terminal oxidases are able to grow with glucose as the carbon source but not with the aerobic substrates succinate or lactate. One of these, GV101, is a deletion mutant of cytochrome o and a point mutation of cytochrome d. The other, GK100, is a total deletion mutant of all the genes for both cytochromes. When these mutants were transformed with a...
