英语翻译
Ricin A-chain is an N-glycosidase that hydrolyzes the adenine ring from a specific adenosine of rRNA.Formycin monophosphate (FMP) and adenyl(3'-->5')guanosine (ApG) were bound to ricin A-chain and their structures elucidated by X-ray crystallography.The formycin ring stacks between tyrosines 80 and 123 and at least four hydrogen bonds are made to the adenine moiety.A residue invariant in this enzyme class,Arg180,appears to hydrogen bond to N-3 of the susceptible adenine.
