Catalysis of the preferential cleavage of Arg-Xaa bonds in small molecule substrates. Highly selective action to release kallidin (lysyl-bradykinin) from kininogen involves hydrolysis of Met-Xaa or Leu-Xaa. The rat enzyme is unusual in liberating bradykinin directly from autologous kininogens by cleavage at two Arg-Xaa bonds.

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

Enables the directed movement of L-serine, the levorotatory isomer of 2-amino-3-hydroxypropanoic acid, into, out of, within or between cells.

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

Enables the directed movement of tryptophan, 2-amino-3-(1H-indol-3-yl)propanoic acid, into, out of, within or between cells.

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.

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 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.

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