Volume-selective water-suppressed proton spectra were recorded from live human brain and muscle at 1.5T by combining a stimulated echo acquisition mode pulse sequence for localization and two saturation pulses for water suppression (Frahm et al., SMR

Phosphorylation of the 20 000-Da light chain of myosin in functionally different porcine carotid arteries was determined, with use of two-dimensional gel electrophoresis. Stretching arteries to 1.7 times their resting length resulted in maximal phosp

These experiments suggest that chondroblasts, cells notoriously sessile, contain considerable amounts of protein (or proteins) that binds ADP in a manner which is indistinguishable from actin. These findings are consistent with the in situ decoration

We used high-resolution two-dimensional electrophoresis to analyze the major proteins of normal and pathological human-muscle samples. The normal human-muscle pattern contains four myosin light chains: three that co-migrate with the myosin light chai

1. (1) Myosin purified by cellulose phosphate chromatography ( Harris and Suelter 24) was treated with 1-fluoro-2,4-dinitro[14C]benzene which resulted in activation of the Ca2+-ATPase activity and inhibition of the EDTA-ATPase activity. The ability o

1. 1.Chicken gizzard Subfragment 1 was isolated from the heavy meromyosin by digestion with papain. This Subfragment 1 appeared as a single peak after chromatography on Sephadex G-200 and DEAE-cellulose. Its migration on disk gel electrophoresis was

The bound Ca of actin readily exchanges with free Ca in G-actin but not in F-actin. The rates of exchange of the Ca and ATP bound to G-actin are similar. As the polymerization of G-actin proceeds, its Ca exchangeability decreases. Chelating agents an

Under ultrasonic vibration the bound Ca of F-actin exchanges with free Ca. The exchange of the F-actin-bound Ca is more rapid than the ATP hydrolysis catalyzed by F-actin under the same conditions. In the presence of ATP the bound Ca of F-actin canno
