Stabilization of the T and R allosteric states of Escherichia coli aspartate transcarbamoylase is governed by specific intra- and interchain interactions. The six interchain interactions between Glu-239 in one catalytic chain of one catalytic trimer with both Lys-164 and Tyr-165 of a different catalytic chain in the other catalytic trimer have been shown to be involved in the stabilization of t...
Analysis of the hystereses in the force-length relationship at constant Ca(2+) concentration and in the force-calcium relationship at constant sarcomere length (SL) provides insight into the mechanisms that control cross-bridge (XB) recruitment. The hystereses are related here to two mechanisms that regulate the number of strong XBs: the cooperativity, whereby the number of strong XBs determine...
The M4 muscarinic acetylcholine (ACh) receptor (mAChR) is a potential therapeutic target but characterized by a lack of subtype-selective ligands. We recently generated "designer receptors exclusively activated by a designer drug" (DREADDs), which contained mutations of two conserved orthosteric-site residues (Y113C/A203G in the M4 mAChR) that caused a loss of ACh activity but a gain in respons...
