Fructose-bisphosphatase as a substrate of cyclic AMP-dependent protein kinase.

We have tested rat liver fructose-bisphosphatase (D-fructose-1,6-bisphosphate 1-phosphohydrolase, EC 3.1.3.11) and three other gluconeogenic fructose-bisphosphatases as substrates for the catalytic...

Phosphorylation and dephosphorylation of dihydropyridine-sensitive voltage-dependent Ca2+ channel in skeletal muscle membranes by cAMP- and Ca2+-dependent processes.

Hosey, M M, Borsotto, M, Lazdunski, M

The phosphorylation and dephosphorylation of the dihydropyridine-sensitive Ca2+ channel was studied in transverse-tubule membranes isolated from rabbit skeletal muscle. Exposure of these membranes to...

Increased ATP inhibition of liver phosphofructokinase from genetically diabetic mice.

Hosey, M M, Chatterjee, T, Cohen, A J, Stein, A L, Kemp, R G, Marcus, F

Phosphofructokinase (ATP:D-fructose-6-phosphate 1-phosphotransferase, EC 2.7.1.11) was partially purified from the livers of genetically diabetic mice (C57BL/KsJ-db) and their lean littermates...

Dihydropyridine-sensitive skeletal muscle Ca channels in polarized planar bilayers. 1. Kinetics and voltage dependence of gating.

Ma, J, Mundiña-Weilenmann, C, Hosey, M M, Ríos, E

Rabbit skeletal muscle transverse tubule (T) membranes were fused with planar bilayers. Ca channel activity was studied with a "cellular" approach, using solutions that were closer to physiological...

Dihydropyridine-sensitive skeletal muscle Ca channels in polarized planar bilayers. 2. Effects of phosphorylation by cAMP-dependent protein kinase.

Mundiña-Weilenmann, C, Ma, J, Ríos, E, Hosey, M M

The effects of phosphorylation on the voltage-dependent properties of dihydropyridine-sensitive Ca channels of skeletal muscle were studied. Single channel currents were recorded upon incorporation...

Dihydropyridine-sensitive skeletal muscle Ca channels in polarized planar bilayers. 3. Effects of phosphorylation by protein kinase C.

Ma, J, Gutiérrez, L M, Hosey, M M, Ríos, E

The effects of protein kinase C (PKC) were studied on dihydropyridine (DHP)-sensitive Ca channels from rabbit skeletal muscle T tubule membranes. To determine which channel subunits become...
