Streptococcus bovis possesses two sugar phosphate phosphatases (Pases). Pase I is a soluble enzyme that is inhibited by the membrane fractions from lactose-grown cells and is insensitive to activation by S46D HPr, an analog of HPr(ser-P) of the sugar phosphotransferase system. Pase II is a membrane-associated enzyme that can be activated 10-fold by S46D HPr, and it appears to play a role in inducer expulsion.
