4.A.3.2.7
N,N'-diacetylchitobiose (cellobiose) PTS permease, CelABC (IIABC).  Essential for normal virulence and biofilm formation by K. pneumoniae which causes pyogenic liver abscesses (Wu et al. 2012).  88% identical to the diacetylchitobiose II (4.A.3.2.1) of E. coli.  These two proteins are probably orthologous.
