Also mischarges tRNA(Asp) with D-aspartate, although it is a poor substrate ; Belongs to the class-II aminoacyl-tRNA synthetase family. Type 1 subfamily. | 0.946 |

argS | ileS | b1876 | b0026 | Arginine tRNA synthetase; Protein involved in tRNA aminoacylation for protein translation. | isoleucyl-tRNA synthetase; Catalyzes the attachment of isoleucine to tRNA(Ile). As IleRS can inadvertently accommodate and process structurally similar amino acids such as valine, to avoid such errors it has two additional distinct tRNA(Ile)-dependent editing activities. One activity is designated as 'pretransfer' editing and involves the hydrolysis of activated Val-AMP. The other activity is designated 'posttransfer' editing and involves deacylation of mischarged Val-tRNA(Ile). | 0.995 |

argS | thrS | b1876 | b1719 | Arginine tRNA synthetase; Protein involved in tRNA aminoacylation for protein translation. | threonyl-tRNA synthetase; Catalyzes the attachment of threonine to tRNA(Thr) in a two- step reaction: L-threonine is first activated by ATP to form Thr-AMP and then transferred to the acceptor end of tRNA(Thr). The rate-limiting step is amino acid activation in the presence of tRNA. The 2'-OH of the acceptor base (adenine 76, A76) of tRNA(Thr) and His-309 collaborate to transfer L-Thr to the tRNA; substitution of 2'-OH of A76 with hydrogen or fluorine decreases transfer efficiency 760 and 100-fold respectively.
