Title: Tetrameric alkaline phosphatase in human liver plasma membranes. Author: Chakrabartty A, Stinson RA. Journal: Biochem Biophys Res Commun; 1985 Aug 30; 131(1):328-35. PubMed ID: 4038299. Abstract: Molecular weights of native membrane-bound alkaline phosphatase released by butanol and by nonionic detergents were more than twice that of the purified dimeric enzyme. Alkaline phosphatase released by phosphatidylinositol-specific phospholipase-C was of both high and low molecular weight: the former was a protomer of a single protein of the same molecular size as monomeric alkaline phosphatase. We conclude that the membrane-bound enzyme is probably a tetramer.[Abstract] [Full Text] [Related] [New Search]
