Autor: Ross J. Solaro, James D. Potter, M J Holroyde

Publikováno v: Journal of Biological Chemistry. 254:6478-6482

Porcine left ventricular cardiac myosin and rabbit white skeletal myosin were phosphorylated by rabbit skeletal myosin light chain kinase and their Ca2+ binding properties were examined by equilibrium dialysis techniques. No significant effect of pho

Fluorescence studies of the interaction of calmodulin with myosin light chain kinase

Autor: J D Johnson, Ross J. Solaro, T H Crouch, M J Holroyde, James D. Potter

Publikováno v: Journal of Biological Chemistry. 256:12194-12198

The interaction of calmodulin with myosin light chain kinase produces an approximately 30% increase in myosin light chain kinase tryptophan fluorescence. This represents the first report of calmodulin-induced structural changes in a protein which it

Publikováno v: Journal of Biological Chemistry. 250:4628-4633

Purified troponin (Tn), the complex of the Ca-2+ binding subunit (TnC), the inhibitory subunit (TnI), and the tropomyosin binding subunit (TnT) binds 4 mol of Ca-2+ per mol. Two sites bind Ca-2+ with a binding constant of 5 times 10-8 M- minus 1, and

Publikováno v: The Biochemical journal. 153(2)

A new improved procedure for the purification of rat hepatic glucokinase (ATP-d-glucose 6-phosphotransferase, EC 2.7.1.2) is given. A key step is affinity chromatography on Sepharose-N-(6-aminohexanoyl)-2-amino-2-deoxy-d-glucopyranose. A homogeneous

Mammalian hexokinases: a system for the study of co-operativity in monomeric enzymes

Autor: A, Cornish-Bowden, B A, Connolly, M, Gregoriou, M J, Holroyde, A C, Storer, I P, Trayer

Publikováno v: Archivos de biologia y medicina experimentales. 12(5)

Kinetic and structural studies have been carried out of two isoenzymes of hexokinase from the rat, hexokinase II and glucokinase. Although both enzymes are monomeric, hexokinase II has a molecular weight double that of glucokinase and resembles a dim
