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 constitutively. These organisms apparently lack the HPr(Ser) kinase and HPr(Ser-P) phosphatase that characterize low-GC Gram-positive bacteria. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-141-1-51
