摘要：

Streptomyces lividans, S. coelicolor and S. griseofuscus were examined for the presence of the enzymes of the phosphoenolpyruvate: sugar phosphotransferase system (PTS). All three species were shown to possess Enzyme I, Hpr and fructose-specific Enzyme II (IIfru) activities. In S. lividans and S. coelicolor, all three PTS enzymes were fructose-inducible, but in S. griseofuscus the system was expressed constructively. These organisms apparently lack the HPr(Ser) kinase and HPr(Ser-P) phosphatase that characterize low-GC Gram-positive bacteria.
