Protein Kinase A Catalytic Subunit ?, Active human
Protein Kinase A Catalytic Subunit β, Active human, Recombinant
cAMP-dependent protein kinase catalytic subunit beta is an enzyme that in humans is encoded by the PRKACB gene. cAMP is a signaling molecule important for a variety of cellular functions. cAMP exerts its effects by activating the protein kinase A (PKA), which transduces the signal through phosphorylation of different target proteins. The inactive holoenzyme of PKA is a tetramer composed of two regulatory and two catalytic subunits. cAMP causes the dissociation of the inactive holoenzyme into a dimer of regulatory subunits bound to four cAMP and two free monomeric catalytic subunits. Four different regulatory subunits and three catalytic subunits of PKA have ...e crebtide substrate peptide per minute per mg protein at 30°c using a final concentration of 50 μm [32p] atp. Group: Enzymes. Synonyms: PKA Catalytic Subunit β, Active human; PKA-Cβ; cAMP-dependent protein kinase; PKACB; PRKACB; PKA C-beta; Protein Kinase A Catalytic Subunit &beta. Purity: > 85% (SDS-PAGE).

Protein Kinase A Catalytic Subunit from Bovine, Recombinant
Protein Kinase A (PKA) catalyzes the transfer of the terminal phosphate of ATP to threonine or serine residues in a variety of protein substrates. The enzyme is composed of two subunit types: a catalytic subunit and a regulatory subunit. In the absence of cAMP, the two subunits are bound to each other and no catalysis can take place. In the presence of cAMP, the regulatory subunit binds cAMP, thus releasing the catalytic subunit. In the presence of cAMP, the catalytic subunit exists as a monomer of 40,862 Da (amino acid sequence), but on SDS-PAGE the apparent molecular mass is 43,000 Da. Group: Enzymes. Synonyms: PKA; cAMP-dependent protein kinase; ATP:protein phosphotransferase (cAMP-dependent); Protein K. Enzyme Commission Number: EC 2.7.11.11. Activity: >9 units/μg protein.
