NametRNA-Asn direct aminoacylation
DescriptionThe tRNA for Asn can be produced in either of two ways: direct aminoacylation with Asn, and misacylation with Asp that is subsequently amidated to Asn. This is analogous to the system for charging tRNA with Gln, and may share some of the same machinery. This property describes a single polypeptide chain tRNA ligase responsible for direct aminoacylation with Asn.
