gtpase meaning in English
纺锤体
Examples
- The execution of rab gtpase biological functiones is also dependent on some effector proteins
Rab蛋白功能的发挥也需要其他的蛋白存在，即所谓的效应蛋白( effector ) 。 - The purity of eorabl protein , cleaved gst - eorabl protein with thrombin protease , reached 95 percent
这为gtpase活性的深入研究，抗体的制备及细胞内定位准备了前提物质。 - Ftsz also be a key cytoplasm moving cell division protein . on the cell membrane division site where it forms a ring - like structure which acts as a framework and disassembled when cell division finished
Ftsz是一个gtp结合蛋白，具有gtpase活性，在依赖gtp时聚合形成丝状体或管，它们在隔膜合成时起骨架作用。 - Surprisingly , in both of archaebacteria and chloroplast , ftsz is the main component in the process of division but it is n ' t effective in mitochodria division , instead is a dynamin protein
此外ftsz还是一种400个残基的保守蛋白， ftsz与真核tubulin在结构、功能和进化上有一定的相似性及同源性，都具gtpase结构域，属于g蛋白家族。 - Rab7 mediates transport of proteins from early endosome to late endosome or fusion of early endosome with late endosome , while rab9 mediates the retransport of m6pr from late endosome to trans - golgi network . the gtp / gdp - binding ability and intrinsic gtpase activity of rab proteins make them exist in rab - gtp or rab - gdp status . the switching of rabs between gtp - bound ( active ) and gdp - bound ( inactive ) forms requires other regulatory proteins , including guanosine exchange factor ( gef ) , gdp dissociation inhibitor ( gdi ) and gtpase activating protein ( gap ) , and lays the foundations of rab function
Rab蛋白家族成员和其他小g蛋白一样可以结合gtp gdp ，在自身gtp酶的水解作用和其他蛋白( gef 、 gap 、 gdi )的调节作用下发生gtp (活化状态)和gdp (无活性)结合形式的转变；同时rab蛋白也在膜结合性( membrane - bound )和胞浆可溶性( cytosolic )之间变化，一个变化过程对应着一个功能循环，接着rab蛋白回到初始状态参与下一个循环。
