8.A.8.1.7
The phosphocarrierprotein of the PTS, HPr (PtsH) of 93 aas. In this organism and another Streptomyces species, S. lividans, HPr and Enzyme I are inducible by fructose (Titgemeyer et al. 1995), and they comprise a complete fructose phosphorylation and transport system (Parche et al. 1999). All pts related genes present in the S. coelicolor genome have been identifed, and in addition to the Fructose PTS described above, there are several other PTS enzyme II complexes, that transport other sugars (Parche et al. 1999) including N-acetylglucosamine which serves as a sensing device as well as a transporter/kinase for N-acetylglucosamine (see TC# 4.A.1.1.20) (Nothaft et al. 2010).
