GO:0005737 The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. GO:0016301 Catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule. GO:0046872 Binding to a metal ion. GO:0008965 Catalysis of the reaction: phosphoenolpyruvate + protein L-histidine = pyruvate + protein N(pi)-phospho-L-histidine. GO:0015764 The directed movement of N-acetylglucosamine into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. 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:0003824 Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
GO:0016310 The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.
GO:0016772 Catalysis of the transfer of a phosphorus-containing group from one compound (donor) to another (acceptor).

PDB and ChEMBL records on this protein are shown in full. ChEMBL records from similar proteins are capped at the top 100 per protein (by pchembl) and ZINC at the top 50 (Tanimoto ≥ 0.5). ADME columns are descriptor-based screening flags, not experimental toxicity results.
