Escherichia coli strains devoid of one or both of the two pyruvate kinase isoenzymes (PKA and PKF), were grown on minimal media in batch fermentations. The strain lacking both PKs showed a 28% decrease on its specific growth rate when compared to the wild type. However, protein and CO 2 yields did n
## Abstract The effects of pH on the kinetic properties of pyruvate kinase were determined for both the aerobic and anoxic (16 hours exposure to N~2~βbubbled seawater) enzyme forms from foot muscle and gill of the marine whelk, __Busycotypus canaliculatum__. The two enzyme forms from each tissue ha
