Unique biochemical properties of the protein tyrosine phosphatase activity of PTEN-demonstration of different active site structural requirements for phosphopeptide and phospholipid phosphatase activities of PTEN.
PTEN catalysis of phospholipid dephosphorylation reaction follows a two-step mechanism in which the conserved aspartate-92 does not function as the general acid--mechanistic analysis of a familial Cowden disease-associated PTEN mutation.
