Activity : ≥3,000 units/mg protein (37°C, pH 9.8, DEA)

summary : Alkaline phosphatase is a broad term associated with non-specific phosphomonesterases with activity optima at alkaline pH.

characteristic : See review by Reid and Wilson (1971). Also Mushak and Coleman (1972) and Snyder and Wilson (1972).

component : The enzyme is a zinc metallo-enzyme. Schüssler (1968) reports four isozymes. Chang and Moog (1972) found three isozymes in the enzyme from chicken duodenum. (The Worthington preparation is from the whole intestine.)
