CC   -!- FUNCTION: The phosphoenolpyruvate-dependent sugar
CC       phosphotransferase system (sugar PTS), a major carbohydrate active
CC       transport system, catalyzes the phosphorylation of incoming sugar
CC       substrates concomitantly with their translocation across the cell
CC       membrane. The enzyme II complex composed of SrlA, SrlB and SrlE is
CC       involved in glucitol/sorbitol transport. It can also use D-
CC       mannitol. {ECO:0000269|PubMed:1100608}.
CC   -!- CATALYTIC ACTIVITY: [Protein]-N(pi)-phospho-L-histidine + D-
CC       sorbitol(Side 1) = [protein]-L-histidine + D-sorbitol 6-
CC       phosphate(Side 2). {ECO:0000269|PubMed:1100608}.
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Kinetic parameters:
CC         KM=44 uM for D-glucitol {ECO:0000269|PubMed:1100608};
CC         KM=60 uM for D-mannitol {ECO:0000269|PubMed:1100608};
CC         Vmax=7.2 nmol/min/mg enzyme with D-mannitol as substrate
CC         {ECO:0000269|PubMed:1100608};
CC         Vmax=0.83 nmol/min/mg enzyme with D-glucitol as substrate
CC         {ECO:0000269|PubMed:1100608};
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000305|PubMed:3553176}; Multi-pass membrane protein
CC       {ECO:0000255, ECO:0000305|PubMed:3553176}.
CC   -!- INDUCTION: Regulated by an unusual system which consists of the
CC       activator GutM and the repressor GutR in addition to the cAMP-CRP
CC       complex. {ECO:0000269|PubMed:3062173}.
CC   -!- DOMAIN: The EIIB domain is phosphorylated by phospho-EIIA on a
CC       cysteinyl or histidyl residue, depending on the transported sugar.
CC       Then, it transfers the phosphoryl group to the sugar substrate
CC       concomitantly with the sugar uptake processed by the EIIC domain.
CC       {ECO:0000255|PROSITE-ProRule:PRU00425}.
CC   -!- SIMILARITY: Contains 1 PTS EIIB type-5 domain.
