Functional Annotations

Enzyme classification and Gene Ontology terms linked to this protein.

10 GO

Gene Ontology (GO)

10
  • GO:0005524 Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
  • GO:0016020 A lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it.
  • GO:0006508 The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.
  • GO:0008233 Catalysis of the hydrolysis of a peptide bond. A peptide bond is a covalent bond formed when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom from the amino group of a second amino acid.
  • GO:0055085 The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other.
  • GO:0008234 Catalysis of the hydrolysis of peptide bonds in a polypeptide chain by a mechanism in which the sulfhydryl group of a cysteine residue at the active center acts as a nucleophile.
  • GO:0140359 Primary active transporter characterized by two nucleotide-binding domains and two transmembrane domains. Uses the energy generated from ATP hydrolysis to drive the transport of a substance across a membrane.
  • GO:0016887 Catalysis of the reaction: ATP + H2O = ADP + H+ phosphate. ATP hydrolysis is used in some reactions as an energy source, for example to catalyze a reaction or drive transport against a concentration gradient.
  • GO:0005886 The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
  • GO:0034040 Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: ATP + H2O + lipid(in) = ADP + phosphate + lipid(out).
