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.

Complex that possesses phosphoribosylaminoimidazole carboxylase activity.

The posttranslational modification of peptidyl-lysine to form hypusine, N6-(4-amino-2-hydroxybutyl)-L-lysine.

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.

The chemical reactions involving guanine, guanine riboside, a nucleoside with a wide species distribution.

Interacting selectivzely with L-ascorbic acid, a six-carbon carbohydrate-like compound found in fruit and vegetables. It has vitamin C activity in humans and guinea pigs.

The chemical reactions involving 7-methylguanosine, a modified nucleoside that forms a cap at the 5'-terminus of eukaryotic mRNA.

Interacting lelectively with cobalamin (vitamin B12), a water-soluble vitamin characterized by possession of a corrin nucleus containing a cobalt atom.

Any process that modulates the frequency, rate or extent of mRNA 3'-end processing, any process involved in forming the mature 3' end of an mRNA molecule.

Catalysis of the covalent attachment of ubiquitin-like proteins to lysine residues on the target protein. This function may be performed alone or in conjunction with an E3, ubiquitin-like protein ligase.
