Modulation of the activity of the enzyme cAMP-dependent protein kinase.

Interacting selectively with lipoic acid, 1,2-dithiolane-3-pentanoic acid.

protein kinase CK2, intrinsic regulator activity

Modulation of the activity of the enzyme protein kinase CK2.

Interacting selectively with a carboxylic acid, any organic acid containing one or more carboxyl (COOH) groups or anions (COO-).

The process by which one or more ubiquitin moieties are added to a protein.

phosphorylase kinase, intrinsic regulator activity

Modulation of the activity of the enzyme phosphorylase kinase.

The alteration of DNA or protein in chromatin, which may result in changing the chromatin structure.

The alteration of DNA or protein in chromatin by the covalent addition or removal of chemical groups.

Enables the directed movement of amino acids, organic acids containing one or more amino substituents, into, out of, within or between cells.

Catalysis of the reaction: 1-acyl-glycerone 3-phosphate + a long-chain alcohol = 1-alkyl-glycerone 3-phosphate + a long-chain acid anion.

Enables the directed movement of acidic amino acids, amino acids with a pH below 7, into, out of, within or between cells.

aromatic amino acid transporter activity

Enables the directed movement of aromatic amino acids, amino acids with aromatic ring, into, out of, within or between cells.

Catalysis of the release of an N-terminal dipeptide, by the hydrolysis of the Xbb-Xcc bond in Xaa-Xbb-Xcc, preferentially when Xbb is Pro, provided Xcc is neither Pro nor hydroxyproline.

Enables the directed movement of basic amino acids, amino acids with a pH above 7, into, out of, within or between cells.

Catalysis of the selective cleavage of Lys6-Ile7 bond in trypsinogen.

Enables the directed movement of neutral amino acids, amino acids with no net charge, into, out of, within or between cells.

Catalysis of the release of mature proteins from their proproteins by cleavage of the terminal bond of Arg-Xaa-Yaa-Arg-Z motifs where Xaa can be any amino acid and Yaa is Arg or Lys. Releases albumin, complement component C3 and von Willebrand factor from their respective precursors.
