toxic residue 中文意思是什麼
toxic residue
解釋
殘毒-
It is toxic for most mammalian cells since ricin a chain ( rta ) is an rna specific n - glycosidase that removes a specific adenine residue in a highly conservative region from among over 4000 nucloside residues present in 28s rrna, and causes protein synthesis inhibition and cell death
Rta具有n -糖苷酶活性,可催化28srrna在4234位脫去腺嘌呤,使核糖體60s亞基失活,從而抑制蛋白質合成,導致細胞死亡。 b鏈( rtb )是結合鏈,能和細胞表面半乳糖受體結合,協助a鏈進入細胞內。
