It inhibits protein synthesis by catalytically inactivating ribosomes. Previously, catalytically or thermally cracked gasolines were most susceptible to oxidation. Each of these protein kinases lead to phosphorylated and catalytically inactive glycogen synthase. PstI is catalytically active as a dimer. These residues interact with catalytically required magnesium ions. The xylan polymers can be hydrolyzed into xylose, which is catalytically hydrogenated into xylitol. Eukaryotic NOS isozymes are catalytically self-sufficient. Mitogen-activated protein kinases are catalytically inactive in their base form. Contains most of the catalytically relevant residues on the enzyme. Usually hydrogenolysis is conducted catalytically using hydrogen gas. Enzymes with this property are called "catalytically perfect" or "kinetically perfect". In various cell types, overexpression of a catalytically inactive Aurora B prevents cytokinesis. The consensus sequence for catalytically active ADAM proteins is HEXGHNLGXXHD. CDKs are catalytically active only when bound to a regulatory cyclin. This recently identified enzyme has a catalytically active site called the Jumonji domain (JmjC).
