Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: (glycoside, pentoside or hexuronide)(out) + monovalent cation(out) = (glycoside, pentoside or hexuronide)(in) + monovalent cation(in). The cation is Na+, Li+ or H+.

Enables the transfer of a glucuronosides from one side of a membrane to the other. Glucuronosides are any compound formed by combination of glycosidic linkage of a hydroxy compound (e.g. an alcohol or a saccharide) with the anomeric carbon atom of glucuronate.

Binding to cholesterol (cholest-5-en-3-beta-ol); the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones.

Enables the transfer of long-chain fatty acids from one side of a membrane to the other. A long-chain fatty acid is a fatty acid with a chain length between C13 and C22. This transporter is a porin and so enables the energy independent passage of substances, sized less than 1000 Da, across a membrane. The transmembrane portions of porins consist exclusively of beta-strands which form a beta-barrel. They are found in the outer membranes of Gram-negative bacteria, mitochondria, plastids and possibly acid-fast Gram-positive bacteria.

OBSOLETE. Any substance that causes the lysis of red blood cells.

Enables the transfer of maltose from one side of a membrane to the other. Maltose is the disaccharide 4-O-alpha-D-glucopyranosyl-D-glucopyranose, an intermediate in the enzymatic breakdown of glycogen and starch. This transporter is a porin so enables the energy independent passage of substances, sized less than 1000 Da, across a membrane. The transmembrane portions of porins consist exclusively of beta-strands which form a beta-barrel. They are found in the outer membranes of Gram-negative bacteria, mitochondria, plastids and possibly acid-fast Gram-positive bacteria.

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

OBSOLETE. Secretins are Gram-negative bacterial outer membrane proteins that form multimeric pores through which macromolecules, usually proteins, can pass. Form homomultimeric ring structures, 10-20 subunits per complex, with large central pores (inner diameters of 5-10 nm).

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

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

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

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

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

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

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

Enables the transfer of ammonium from one side of a membrane to the other, up its concentration gradient. The transporter binds the solute and undergoes a series of conformational changes. Transport works equally well in either direction and is driven by a chemiosmotic source of energy. Secondary active transporters include symporters and antiporters. In high-affinity transport the transporter is able to bind the solute even if it is only present at very low concentrations.

Enables the transfer of a nucleoside, from one side of a membrane to the other, down the concentration gradient.
