ABSTRACT
Pasteurella multocida was examined for glucose and mannose transport. P. multocida was shown to possess a phosphoenolpyruvate (PEP)mannose phosphotransferase system (PTS) that transports glucose as well as mannose and was functionally similar to the Escherichia coli mannose PTS. Phosphorylated proteins with molecular masses similar to those of E. coli mannose PTS proteins were visualized when incubated with 32P-PEP. The presence of an enzyme IIAGlc which could play an important role in regulation, as described in other Gram-negative bacteria, was detected. The enzymes of the pentose-phosphate pathway were present in P. multocida growth on glucose. The activity of 6-phosphofructokinase (the key enzyme of the Embden-Meyerhof pathway (EMP)), was very low in cell extracts, suggesting that EMP is not the major pathway for glucose catabolism.
