1 5"-Nucleotidase activity was inhibited by adenosine 5"-[alpha,beta-methylene]diphosphate and concanavalin A, followed simple Michaelis-Menten kinetics and was released from the membranes by treatment with phosphatidylinositol-specific phospholipase C, indicating that AMP hydrolysis in T-tubules is catalysed by a typical ecto-5"-nucleotidase. alpha,beta-methyleneadenosine 5'-diphosphate 5'-nucleotidase ecto Gallus gallus
