enzymatic reactions catalyzed by IleRS include amino acid activation, tRNA binding, aminoacyl transfer, and dissociation of aminoacylated tRNA from the enzyme, in the synthetic pathway. Pretransfer editing may proceed through enhanced dissociation of noncognate aminoacyl-AMP (1) or through its enzymatic hydrolysis, which may be tRNA-independent (2) ortRNA-dependent (3). Misacylated tRNA is deacylated through posttransferediting, overview
