CommentThis HMM describes a full-length protein of about 160 residues closely related to the fructose-specific phosphotransferase (PTS) system IIA component. It is a regulatory protein found only in species with a phosphoenolpyruvate-protein phosphotransferase (enzyme I of PTS systems) and an HPr-like phosphocarrier protein, but not all species have a IIC-like permease. Members of this family are found in Proteobacteria, Chlamydia, and the spirochete Treponema pallidum.
