>gnl|CDD|29821 cd00776, AsxRS_core, Asx tRNA synthetase (AspRS/AsnRS) class II core domain. Assignment to class II aminoacyl-tRNA synthetases (aaRS) based upon its structure and the presence of three characteristic sequence motifs in the core domain. This family includes AsnRS as well as a subgroup of AspRS. AsnRS and AspRS are homodimers, which attach either asparagine or aspartate to the 3'OH group of ribose of the appropriate tRNA. While archaea lack asnRS, they possess a non-discriminating aspRS, which can mischarge Asp-tRNA with Asn. Subsequently, a tRNA-dependent aspartate amidotransferase converts the bound aspartate to asparagine. The catalytic core domain is primarily responsible for the ATP-dependent formation of the enzyme bound aminoacyl-adenylate.. Length = 322
