bound ribosome meaning in English

固着核糖体

Many glycoproteins of lower and higher eucaryotes are attached to the plasma membrane by means of a glycosylphosphatidylinositol ( gpi ) . gpi - anchored proteins are synthesized on membrane - bound ribosomes . upon translocation of the pro - protein across the endoplasmic reticulum membrane , gpi : protein transamidase ( gp1t ) recognize and removes the carboxy terminal gpi signal sequence and attaches a gpi molecule to the newly exposed carboxy terminal amino acid
Gpi化前体蛋白在依附于膜的核糖体上合成，当其易位穿过内质网( er )膜后，被gpi ：蛋白质转酰胺基酶( gpit )识别， gpit在移走其羧基端gpi信号序列的同时将gpi分子连接至新生成的氨基酸位点上。
