GO
GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. GO:0005355 OBSOLETE. Enables the transfer of the hexose monosaccharide glucose from one side of a membrane to the other. GO:0009401 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. GO:0008982 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:1904659 The process in which D-glucose is transported across a membrane.
