查询词典 allosteric

Only when theenzyme was saturated by dCMP or allosteric activator dCTP, dAMPbehaved as a net isosteric competitive inhibitor.

只有当此酶被dCMP或别构激活剂dCTP饱和时，dAMP才表现出纯的同构竞争性抑制作用，其抑制常数为4×10~(-5)M，此值远低于T型和R型构象对dCMP的米氏常数。

Upon binding ATP or a nonhydrolyzable analog such as AMPPNP, RecA undergoes an allosteric transition into a high-affinity DNA-binding form. When RecA combines with dsDNA to form RecA-dsDNA nucleofiliment, it can unwind dsDNA and change the dsDNA structure.

在ATP或其类似物的辅助下，RecA可以直接与双股DNA结合而形成核丝，并将双股DNA加以解螺旋，并改变双股DNA的结构。

Previous studies by others and this laboratory on the allosteric effect of hem oglobins have suggested that the electrostatic replusive cavity at the center of tetrameric moiety plays a substantial role in regulating O2 transport prope rties, including chloride binding, and Bohr effect .

中文摘要过去对血红蛋白异位调节效应的研究指出，在血红蛋白四合体中央空腔的区域的静电排斥效应对分子机能的调节如氧合时氯离子的键结和波尔效应，扮演著一个很重要的角色。

Here we show that signal peptides have a new role beyond targeting: they are essential allosteric activators of the translocase.

在这里我们展示了信号肽除了靶向作用外的新的作用：他们是转移酶的重要的变构激活剂。

A role for signal peptides and targeting sequences as allosteric activators may be universal in protein translocases.

这种信号肽在对转移酶的变构激活中的作用可能是普遍的。

It is an allosteric enzyme.

它是一个别构酶。

A fundamental goal in signal transduction study is to understand allosteric communication .

对变构通讯的理解是研究细胞信号转导的一个基本目标。

Allosteric enzymes may have more than one modulator.

它可以有一个或多个调节物。

Here we show that allosteric proteins can be regulated predominantly by changes in their structural dynamics.

他们出乎意料地发现，即便是当处在一个从结构上来讲没有活性的构形时，CAP也能被蛋白动态的变化所激活，以便与配体结合。

The results show that CaM without antagonist tends to open from its closed state and cause allosteric interaction.

在此基础上，进一步用靶向分子动力学模拟了CaM从闭合到打开的构象变化过程，得到一条稳定的变化路径和4个可能的过渡态构象。

She gently rebuff ed him, but agreed that they could be friends
