Descriptions Names[Advanced Search]

Primary active transport of a solute across a membrane, driven by the hydrolysis of the diphosphate bond of inorganic pyrophosphate, ATP, or another nucleoside triphosphate. The transport protein may or may not be transiently phosphorylated, but the substrate is not phosphorylated. Primary active transport is catalysis of the transport of a solute across a membrane, up the solute's concentration gradient, by binding the solute and undergoing a series of conformational changes. Transport works equally well in either direction and is driven by a primary energy source. Catalysis of the reaction: ATP + H2O + polyamine(out) = ADP + phosphate + polyamine(in). Catalysis of the reaction: ATP + H2O = ADP + phosphate to directly drive the active transport of a substance across a membrane. Catalysis of the transfer of amines, including polyamines, from one side of the membrane to the other. Amines are organic compounds that are weakly basic in character and contain an amino (-NH2) or substituted amino group. Catalysis of the hydrolysis of an acid anhydride to directly drive the transport of a substance across a membrane. Catalysis of the transfer of polyamines, organic compounds containing two or more amino groups, from one side of the membrane to the other. Catalysis of the reaction: ATP + H2O + putrescine(out) = ADP + phosphate + putrescine(in). Catalysis of the reaction: ATP + H2O + spermidine(out) = ADP + phosphate + spermidine(in). Catalysis of the reaction: ATP + H2O = ADP + phosphate to directly drive the transport of a substance.
