4.A.3.2.11
Cellobiose PTS transporter with one IIC protein, CelC1, of 435 aas and 10 predicted TMSs(Q8Y3Z4, and two sets of IIAB proteins, CelA1 (100 aas; Q927F6) and CelB1 (101 aas; Q8Y3Z5) as well as CelA2 (100 aas; Q92AT9) and CelB2 (102 aas; Q8Y6G7). Another IIC-like protein was also found (454 aas; 10 TMSs; Q8Y3X1)  but it did not phosphorlyate cellobiose, and its function was not identified. Transcription of these genes is regulated by CelR (Cao et al. 2019).
