The role of TNP-Nucleotides, LYS492 and CA²⁺chelators in the skeletal muscle sarcoplasmic reticulum CA²⁺atpase cycle
… in the catalytic cycle of the skeletal muscle Ca²⁺ATPase. It has been found previously, and verified here, that tethering TNP-8N₃-AMP to the Ca²⁺ATPase via Lys492 retarded the Ca²⁺ initiated decay of Pᵢ-induced superfluorescence 10-fold compared with untethered nucleotide. The rapidity of the …

Thermodynamic effects of phospholamban on Ca-ATPase kinetics
The Ca-ATPase of sarcoplasmic reticulum removes cytosolic calcium to promote muscle relaxation. In the heart, the Ca-ATPase is regulated by phospholamban, which inhibits the Ca-ATPase by decreasing Ca-ATPase calcium sensitivity. However, the kinetic and thermodynamic mechanisms of inhibition are …

A Ca²⁺-activated proteinase in chicken skeletal muscle
… calcium dependence (maximum activity at 1.0 rnM Ca²⁺), pH optimum (7.2) and sensitivity to proteinase inhibitors (inhibited by leupeptin and chymostatin). Both embryonic and adult enzymes were found to have molecular weights of 112000 daltons by gel filtration on Sephadex G-150. CAP activity was …

Service Differentiation Using Managed Sleep in CSMA/CA Networks
Performance of multimedia and real-time applications such as streaming video and voice over IP is easily degraded by a high network traffic load. Current Internet infrastructure provides no special assistance for these sensitive applications. One solution to this problem is to introduce Quality of …
