Characterization of a caldesmon fragment that competes with myosin-ATP binding to actin.
(East Carolina University, 1993-08)
The protein caldesmon inhibits actin-activated ATP hydrolysis of myosin and inhibits the binding of myosin*ATP to actin. Afragment isolated from a chymotryptic digest of caldesmon contains features of the intact molecule ...
Deoxyguanosine-resistant Leukemia L1210 Cells: Loss of Specific Deoxyribonecleoside Kinase Activity
(East Carolina University, 1993-01-05)
A mouse leukemia L1210 cell line was selected for resistance to deoxyguanosine. The deoxyguanosine-resistant cells (dGuo-R) were 126-fold less sensitive to deoxyguanosine than the wild-type cells. The IC50 values for araC ...
