Enables the directed movement of L-proline, pyrrolidine-2-carboxylic acid, into, out of, within or between cells.

Catalysis of the release of an N-terminal tripeptide from a polypeptide.

Catalysis of the preferential cleavage of Arg-Xaa, Lys-Xaa.

Enables the directed movement of peptides, compounds of two or more amino acids where the alpha carboxyl group of one is bound to the alpha amino group of another, into, out of, within or between cells.

Catalysis of the hydrolysis of peptide linkages in oligopeptides or polypeptides by a reaction mechanism in which threonine residues act as nucleophiles.

Enables the directed movement of oligopeptides into, out of, within or between cells. Oligopeptides are molecules that contain a small number (2 to 20) of amino-acid residues connected by peptide linkages.

A vesicle formed of membrane or protein, found in the cytoplasm of a cell.

The formation from simpler components of lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent.

The breakdown into simpler components of S-adenosylhomocysteine, forming homocysteine and then methionine.

Complex that possesses phosphoribosylaminoimidazole carboxylase activity.

The formation from simpler components of ether lipids, lipids that contain (normally) one fatty alcohol in ether linkage to one of the carbon atoms (normally C-1) of glycerol.

The chemical reactions involving pyridoxine, 2-methyl-3-hydroxy-4,5-bis(hydroxymethyl)pyridine, one of the vitamin B6 compounds. Pyridoxal, pyridoxamine and pyridoxine are collectively known as vitamin B6, and are efficiently converted to the biologically active form of vitamin B6, pyridoxal phosphate.

The formation from simpler components of pyridoxine, 2-methyl-3-hydroxy-4,5-bis(hydroxymethyl)pyridine, one of the vitamin B6 compounds.

The formation from simpler components of queuosines, any of a series of nucleosides found in tRNA and having an additional pentenyl ring added via an NH group to the methyl group of 7-methylguanosine. The pentenyl ring may carry other substituents.
