4.A.3.2.12
PTS gentiobiose (glucosyl β-1,6-glucose) transporter, subunit IIC of 444 aas and 10 TMSs.  May also transport several other beta-glucosides including inaribiose (β-1,3), chitobiose (NAcGlu-β-1,4), N(4)-β-Nacetyl-D-glucosaminyl-L-Asn (asparagine), chitobiose (NAG-β-1,4-NAG) and sophorose (β-1,2) (Combret et al. 2025). This PTS system is under the control of CelR, a LevR-like transcriptional activator (Combret et al. 2025). It uses IIA and IIB proteins from another PTS transporter, CelA1 and CelB1 (see TC# 4.A.3.2.13).
