Trna aminoacylation
Research into the stability of aa-tRNAs illustrates that the acyl (or ester) linkage is the most important conferring factor, as opposed to the sequence of the tRNA itself. This linkage is an ester bond that chemically binds the carboxyl group of an amino acid to the terminal 3'-OH group of its cognate tRNA. It has been discovered that the amino acid moiety of a given aa-tRNA provides for its structural integrity; the tRNA moiety dictates, for the most part, how and when th… WebAbstract.
