ATP has dual roles in the reaction cycle of sarcoplasmic reticulum Ca(2+)-ATPase. Upon binding to the Ca2E1 state, ATP phosphorylates the enzyme, and by binding to other conformational states in a non-phosphorylating modulatory mode ATP stimulates th

Udgivelsesdato: 2008-Dec-19 ATP plays dual roles in the reaction cycle of the sarcoplasmic reticulum Ca(2+)-ATPase by acting as the phosphorylating substrate as well as in nonphosphorylating (modulatory) modes accelerating conformational transitions

In recent years crystal structures of the sarcoplasmic reticulum Ca(2+)-ATPase (SERCA1a), stabilized in various conformations with nucleotide and phosphate analogs, have been obtained. However, structural analysis of mutant forms would also be valuab

Crystal structures have shown that the conserved TGES loop of the Ca2+-ATPase is isolated in the Ca2E1 state but becomes inserted in the catalytic site in E2 states. Here, we have examined the kinetics of the partial reaction steps of the transport c

Point mutants with alterations to amino acid residues Thr(247), Pro(248), Glu(340), Asp(813), Arg(819), and Arg(822) of sarcoplasmic reticulum Ca(2+)-ATPase were analyzed by transient kinetic measurements. In the Ca(2+)-ATPase crystal structures, mos

Understanding of Ca(2+) signaling requires the knowledge of proteins involved in this process. Among these proteins are sarco/endoplasmic reticulum Ca(2+)-ATPases (SERCAs) that pump Ca(2+) into the endoplasmic reticulum (ER). Recently, the human SERC

Nine single mutations were introduced to amino acid residues Thr441, Glu442, Lys515, Arg560, Cys561, and Leu562 located in the nucleotide-binding domain of sarcoplasmic reticulum Ca2+-ATPase, and the functional consequences were studied in a direct n
