aminoacyl-tRNA


a·mi·no·ac·yl-tRNA

(ă-mē'nō-as'il), Generic term for those compounds in which amino acids are esterfied through their COOH groups to the 3'- (or 2'-) OHs of the terminal adenosine residues of transfer RNAs (for example, alanyl-tRNA, glycyl-tRNA); each compound involves one, or a small number, of tRNAs of specific chemical structure. Used in protein biosynthesis.

aminoacyl-tRNA

the molecule produced when an AMINO ACID is activated into its aminoacyl form and attached to its specific TRANSFER RNA molecule, the whole process being catalysed by a specific aminoacyl-tRNA synthetase enzyme. Also called charged tRNA.
