A placental example of these enzymes is a diagnostic marker of seminomas (“seh-min-OH-mahs”). NEB’s “Antarctic” form of one of these enzymes conveniently inactivates at 80 degrees Celsius. Staining for a tartrate-resistant form of one of these enzymes is diagnostic of hairy cell leukemia. Excessive bone formation and elevation of another one of these enzymes in the blood are diagnostic of Paget’s (“PAA-jitz”) disease. CSPD and PNPP are common substrates for one of these enzymes in ELISA (“eliza”). One of these enzymes extracted from calf intestines prevents recircularization of plasmids after restriction digestion. When the level of one of these enzymes is elevated, high gamma-glutamyl transferase levels confirm a biliary source. Insulin activates protein kinase B and one of these enzymes called PP1 to induce glycogen synthesis. For 10 points, name these enzymes that reverse the action of kinases by removing phosphate groups. ■END■
ANSWER: phosphatases (“FOSS-fah-TACEs”) [accept protein phosphatases, alkaline phosphatases, acid phosphatases, calf-intestinal alkaline phosphatase, Antarctic Phosphatase, or placental alkaline phosphatase; reject “dephosphorylases”]
