| 1 | In the present paper, we report that purification of the NTPase from both muscle sources resulted in an alteration in the NTP concentration response compatible with a single high affinity binding site for ATP only in cardiac SR and for both substrates in skeletal muscle SR. As is the case with native skeletal muscle SR, purified skeletal muscle NTPase hydrolyzed GTP in a manner qualitatively similar to ATP (but with no Ca2+-independent NTPase) but with reduced velocity. | ntp | inosine triphosphatase | Homo sapiens |

| 8 | We suggest that GTPase and basic ATPase represent similar alternative enzyme cycles for the CaATPase enzyme that are inhibited by the presence of ATP plus Ca2+ but are rendered inactive during the purification of cardiac NTPase. | Adenosine Triphosphate | inosine triphosphatase | Homo sapiens |
