Phosphatase signal transduction
WebA protein phosphatase is a phosphatase enzyme that removes a phosphate group from the phosphorylated amino acid residue of its substrate protein. Protein phosphorylation is one of the most common forms of reversible protein posttranslational modification ( PTM ), with up to 30% of all proteins being phosphorylated at any given time.
