Short name: Asp-tRNA-ligase_1

Family relationships

Description

Aspartate tRNA ligase (also known as Aspartyl-tRNA synthetase) EC:6.1.1.12 is an alpha2 dimer that belongs to class IIb. Structural analysis combined with mutagenesis and enzymology data on the yeast enzyme point to a tRNA binding process that starts by a recognition event between the tRNA anticodon loop and the ligase anticodon binding module [PMID: 10873455].

This family represents aspartate-tRNA ligases from most bacteria and eukaryotic mitochondria. In some species, this enzyme aminoacylates tRNA for both Asp and Asn; Asp-tRNA(asn) is subsequently transamidated to Asn-tRNA(asn).
