The chemical reactions involving tRNA, transfer RNA, a class of relatively small RNA molecules responsible for mediating the insertion of amino acids into the sequence of nascent polypeptide chains during protein synthesis. Transfer RNA is characterized by the presence of many unusual minor bases, the function of which has not been completely established.

Catalysis of the hydrolysis of Xaa-Pro dipeptides; also acts on aminoacyl-hydroxyproline analogs. No action on Pro-Pro.

Catalysis of the hydrolysis of nonterminal peptide linkages in oligopeptides or polypeptides by a reaction mechanism involving a serine residue (and a histidine residue) at the active center of the enzyme.

Catalysis of the reaction: acylaminoacyl-peptide + H2O = acylamino acid + peptide.

Any complex of actin, myosin, and accessory proteins.

The region of a mitochondrion to which the DNA is confined.

Enables the directed movement of L-alanine, the levorotatory isomer of 2-aminopropanoic acid, into, out of, within or between cells.

Catalysis of the preferential cleavage of Leu-Xaa, Met-Xaa and Phe-Xaa. Hydrolyzes elastin.

Enables the directed movement of L-asparagine, alpha-aminosuccinamic acid, into, out of, within or between cells.

Catalysis of the preferential cleavage of Lys-Xaa

Enables the directed movement of L-aspartate, the anion derived from aspartic acid, into, out of, within or between cells.

Enables the directed movement of L-cystine (also known as dicysteine) into, out of, within or between cells.

Catalysis of the release of protein hormones, neuropeptides and renin from their precursors, generally by cleavage of -Lys-Arg-Xaa at the Arg-Xaa bond.

Enables the directed movement of L-gamma-aminobutyric acid (4-aminobutyrate, GABA) into, out of, within or between cells.

Catalysis of the release of protein hormones and neuropeptides from their precursors, generally by cleavage of -Lys-Arg-Xaa at the Arg-Xaa bond.

Enables the directed movement of L-glutamine, 2-amino-4-carbamoylbutanoic acid, into, out of, within or between cells.
