Enables the transmembrane transfer of a calcium ions by a channel that opens when a specific ligand has been bound by the channel complex or one of its constituent parts.

A ligand-gated ion channel activity which transports calcium in response to emptying of intracellular calcium stores.

An ionotropic glutamate receptor activity that exhibits fast gating by glutamate, acts by opening a cation channel permeable to sodium and potassium, and for which kainate is an agonist.

Enables the transmembrane transfer of a chloride ion by a voltage-gated channel. The membrane is an organellar membrane.

Enables the transmembrane transfer of a potassium ion by an inwardly-rectifying voltage-gated channel, where the inward rectification is due to a voltage-dependent block of the channel pore by ATP. An inwardly rectifying current-voltage relation is one where at any given driving force the inward flow of K+ ions exceeds the outward flow for the opposite driving force.

OBSOLETE. Catalysis of the transport of electrolytes and other small molecules across a cell membrane. They are synthesized by one cell and secreted for insertion into the membrane of another cell where they form transmembrane pores. They may exert their toxic effects by allowing the free flow of electrolytes and other small molecules across the membrane, or they may allow entry into the target cell cytoplasm of a toxin protein that ultimately kills the cell.

OBSOLETE. This term was not defined before being made obsolete.

Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: fructose(out) = fructose(in).

OBSOLETE. This term was not defined before being made obsolete.

Enables the active transport of a solute across a membrane by a mechanism whereby two or more species are transported in opposite directions in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy. The reaction is: solute A(out) + solute B(in) = solute A(in) + solute B(out).

Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: monovalent cation(out) + H+(in) = monovalent cation(in) + H+(out).

Enables the active transport of a solute across a membrane by a mechanism whereby two or more species are transported together in the same direction in a tightly coupled process not directly linked to a form of energy other than chemiosmotic energy.

Any process that stops, prevents or reduces the frequency, rate or extent of heptadecane metabolic process.
