调节部位

ATP结合部位是固氮酶的调节部位；乙炔还原活性部位是固氮酶的催化部位；

ATP binding sites are regulatory sites in the nitrogenase and the acetylene reduction active sites are catalytic sites in the nitrogenase .

根据调节部位信号，自动控制阀门的开度，从而达到介质流量、压力和液位的调节。

According to regulate parts of the signal , the automatic control of valve opening , so as to achieve medium flow rate , pressure and level of regulation .

然而该假说缺乏K~+等物质在渗透调节的关键部位&保卫细胞液泡中积累或耗散的直接证据。

However , it is hard to find out direct evidences for the accumulation of foreign K + in guard cell vacuoles for stomatal opening to satisfy the chemiosmotic hypothesis .

结论：TGF-β参与和调节骺软骨各部位软骨细胞增殖活动，并能诱导非增殖软骨细胞表达PCNA，用PCNA作为细胞增殖的指标是不适宜的。

These data suggest that TGF β participates in and modulates chondrocyte proliferation in varied epiphyseal zones , and it could induce the expression of PCNA in non proliferation chondrocyte , therefore PCNA immunohistochemical staining is not suitable for the detection of proliferation .
