Cys-tRNA(Pro)/Cys-tRNA(Cys) deacylase YbaK

UniProtKB accession:  P0AAR3

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Functions in trans to edit the amino acid from incorrectly charged Cys-tRNA(Pro) via a Cys-tRNA(Pro) deacylase activity. May compensate for the lack of Cys-tRNA(Pro) editing by ProRS. Is also able to deacylate Cys-tRNA(Cys), and displays weak deacylase activity in vitro against Gly-tRNA(Gly), as well as, at higher concentrations, some other correctly charged tRNAs. Unlike some of its orthologs it is not able to remove the amino acid moiety from incorrectly charged Ala-tRNA(Pro).
