it is suggested that tightly bound calcium is located in a hydrophobic pocket in , or in close proximity to the atpase , and , together with tightly bound adenine nucleotides ( aderem , a. , mcintosh , d. b. , and berman , m. c. ( 1979 ) proc . natl . acad . sci . u. s. a . 76 , 3622-03632 ) , is related to the ability of the atpase to couple hydrolysis of atp to vectorial transfer of calcium across the membrane .
