Chain A,B,C,D,E,F,G,H,I (Q81X08_BACAN | Q81X08)

molecular function
	GO:0103111	D-glucosamine PTS permease activity	Catalysis of the reaction: a [PTS enzyme I]-Npi-phospho-L-histidine + D-glucosamine <=> D-glucosamine 6-phosphate + a [PTS enzyme I]-L-histidine
	GO:0008982	protein-N(PI)-phosphohistidine-sugar phosphotransferase activity	Catalysis of the PEP-dependent, phosphoryl transfer-driven transport of substances across a membrane. The transport happens by catalysis of the reaction: protein N-phosphohistidine + sugar(out) = protein histidine + sugar phosphate(in). This differs from primary and secondary active transport in that the solute is modified during transport.
	GO:0016740	transferase activity	Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
	GO:0034219	carbohydrate transmembrane transport	The process in which a carbohydrate is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
	GO:0019533	cellobiose transport	The directed movement of cellobiose into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Cellobiose, or 4-O-beta-D-glucopyranosyl-D-glucose, is a disaccharide that represents the basic repeating unit of cellulose.
	GO:0009401	phosphoenolpyruvate-dependent sugar phosphotransferase system	The uptake and phosphorylation of specific carbohydrates from the extracellular environment; uptake and phosphorylation are coupled, making the PTS a link between the uptake and metabolism of sugars; phosphoenolpyruvate is the original phosphate donor; phosphoenolpyruvate passes the phosphate via a signal transduction pathway, to enzyme 1 (E1), which in turn passes it on to the histidine protein, HPr; the next step in the system involves sugar-specific membrane-bound complex, enzyme 2 (EII), which transports the sugar into the cell; it includes the sugar permease, which catalyzes the transport reactions; EII is usually divided into three different domains, EIIA, EIIB, and EIIC.
