查询词典 narrow passage

The 20S catalytic core of the 26S proteasome has the shape of a barrel made of four rings which are composed of seven differentαsubunitsα_1-α_7 at two outer rings and seven differentβsubunitsβ_1-β_7 at two inner rings at which the catalytic sites locate. Three of theβsubunits contain proteolyses sites, which are sequestered in the hollow interior of the 20S particle. Substrates enter the 20S through a narrow channel formed by theβsubunits, whose N-termini, depending on their conformation, can either obstruct or allow substrate entry and thus function as a gate. This entry channel is narrow and only permits passage of unfolded, linearized polypeptides.

哺乳动物26S蛋白酶体是由一个20S催化颗粒(catalytic particle，CP)和两个19S调节颗粒(regulatory particle，RP)组成的ATP(adenosine-triphosphate，ATP)依赖性蛋白水解酶复合体。20S CP是26S蛋白酶体的催化核心，它是由4个圆环堆叠形成的桶状复合物，其中两侧外环每个环是由α_1-α_7亚基组成，两个内环每个环是由β_1-β_7亚基组成，4个环的中央形成一个狭窄的内腔。2个β内环形成了20S CP的催化中心空腔，其内壁为催化活性位点所在地；外侧α环中心的孔道是底物到达催化中心空腔的通道，一般被α亚基上的N末端所封闭，阻止胞内非目的靶蛋白进入20S CP内被降解破坏。

First super-low specific-speed centrifugal pump has a long and narrow flow passage for its high head and low capacity, and the power absorbed by disc friction is too high, so the efficiency is very low; Secondly the diffusion of flow passage is so high, that the reserved flow often emerges at the inlet and outlet of impeller. Therefore the H ~ Q characteristic curve is often hump-shaped, and at the low-capacity operating condition the instability often occurs; Thirdly the centrifugal pump at high-capacity operating condition is easy to overload because the N ~ Q curve appears a rising trend.

首先由于它的扬程较高、流量较小，所以它的流道狭长，圆盘摩擦损失较大，效率相对较低；其次由于它的流道扩散较严重，易在叶片进口产生回流和在出口产生脱流，扬程流量特性曲线易出现驼峰，在小流量工况下易产生不稳定现象；第三，由于其功率流量曲线呈现上升趋势，在大流量区运行时电机易过载。
