Cyclic GMP-Dependent Protein KinasesA group of enzymes that are dependent on cyclic GMP and catalyzes the phosphorylation of serine or threonine residues of proteins.
EnzymesBiological molecules that possess catalytic activity. They may occur naturally or be synthetically created. Enzymes are usually proteins, however catalytic RNA (RNA, CATALYTIC) and catalytic DNA (DNA, CATALYTIC) molecules have also been identified.
PhosphorylationThe introduction of a phosphoryl group into a compound through the formation of an ester bond between the compound and a phosphorus moiety.
SerineA non-essential amino acid occurring in natural form as the L-isomer. It is synthesized from GLYCINE or THREONINE. It is involved in the biosynthesis of PURINES, PYRIMIDINES, and other amino acids.
ThreonineAn essential amino acid occurring naturally in the L-form, which is the active form. It is found in eggs, milk, gelatin, and other proteins.
