Aspartyl-tRNA synthetase, archaeal-type (IPR004523)

Short name: Asp-tRNA_synthase_arc

Family relationships

Description

Aspartyl tRNA synthetase 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 synthetase anticodon binding module [PMID: 10873455].

This family represents a group of the aspartyl-tRNA synthetases from the eukaryotic cytosol and from archaea. In some species, this enzyme aminoacylates tRNA for both Asp and Asn; Asp-tRNA (asn) is subsequently transamidated to Asn-tRNA (asn).
