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).
