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.

osmosensory signaling pathway via two-component system

osmosensory signalling pathway via two-component system

A series of molecular signals generated in response to osmotic change, as mediated through a two-component (phosphorelay) system.

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 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.
