  • GO:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
  • GO:0005524 Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
  • GO:0033785 Catalysis of the reaction: D-alpha,beta-D-heptose-7-phosphate + ATP = D-beta-D-heptose-1,7-bisphosphate + ADP.
  • GO:0033786 Catalysis of the reaction: D-beta-D-heptose-1-phosphate + ATP = ADP-D-glycero-D-manno-heptose.
  • GO:0016773 Catalysis of the transfer of a phosphorus-containing group from one compound (donor) to an alcohol group (acceptor).
  • GO:0097171 The chemical reactions and pathways resulting in the formation of ADP-L-glycero-beta-D-manno-heptose, an ADP-L-glycero-D-manno-heptose having beta-configuration at the anomeric centre of the heptose. ADP-L-glycero-beta-D-manno-heptose (also called ADP-L-beta-D-heptose or ADP-L-glycero-D-manno-heptose) is a nucleotide-sugar precursor of the inner core lipopolysaccharide (LPS) from D-glycero-beta-D-manno-heptose 7-phosphate.
  • GO:0009244 The chemical reactions and pathways resulting in the formation of the core region of bacterial lipopolysaccharides, which contains ten saccharide residues.
  • 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:0005975 The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y.
  • GO:0016779 Catalysis of the transfer of a nucleotidyl group from one compound (donor) to another (acceptor).
  • GO:0016301 Catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule.
  • GO:0009058 A cellular process consisting of the biochemical pathways by which a living organism synthesizes chemical substances. This typically represents the energy-requiring part of metabolism in which simpler substances are transformed into more complex ones.
