adj.变构(像)的，空间异构的，变构性的

The allosteric regulation of enzymes involves a change in their shape, allowing them to bind different molecules at different sites.
酶的别构调节涉及其形状的变化，使它们能够在不同的位点结合不同的分子。
Allosteric effect occurs when a ligand binds to one site on a protein, causing a conformational change that affects the protein's activity at another site.
别构效应是指配体与蛋白质上一个位点结合后，导致蛋白质构象改变，进而影响其在其他位点的活性。
In hemoglobin, an allosteric protein, binding of oxygen at one heme group influences the affinity for oxygen at the other heme groups.
在血红蛋白这种别构蛋白中，一个血红素组分结合氧气会影响其他血红素组分对氧的亲和力。
G-proteins are involved in allosteric signaling pathways, where a small molecule binds to the G-protein, altering its conformation and activating or inhibiting downstream effector proteins.
G蛋白参与别构信号途径，小分子通过与G蛋白结合，改变其构象，从而激活或抑制下游效应蛋白。
The allosteric modulation of ion channels is crucial for controlling the flow of ions across cell membranes.
离子通道的别构调节对于控制细胞膜内外离子流动至关重要。
In muscles, the binding of calcium ions to troponin is an allosteric event that triggers muscle contraction.
在肌肉中，钙离子与肌钙蛋白的结合是触发肌肉收缩的别构事件。
Allosteric drugs work by binding to a different site than the primary active site, affecting the protein's overall function.
别构药物通过与主要活性位点以外的位点结合，从而影响蛋白质的整体功能。
The allosteric enzyme phosphofructokinase-1 (PFK-1) has two regulatory sites that allow it to adjust its activity according to cellular energy needs.

The allosteric antagonist of a receptor blocks its activation without competing with the natural ligand for the same binding site.
受体的别构拮抗剂阻止其激活，但不会与天然配体竞争同一结合位点。
Allosteric enzymes can exhibit positive or negative cooperativity, meaning that binding of one substrate molecule increases or decreases the affinity for additional substrate molecules, respectively.
别构酶可以表现出正协同或负协同，即一个底物分子的结合会增加或减少对其他底物分子的亲和力。
