EC 3.1.1.96     
Accepted name: D-aminoacyl-tRNA deacylase
Reaction: a D-aminoacyl-tRNA + H2O = a D-amino acid + tRNA
Other name(s): Dtd2; D-Tyr-tRNA(Tyr) deacylase; D-Tyr-tRNATyr deacylase; D-tyrosyl-tRNATyr aminoacylhydrolase; dtdA (gene name)
Systematic name: D-aminoacyl-tRNA aminoacylhydrolase
Comments: The enzyme from Escherichia coli can cleave D-tyrosyl-tRNATyr, D-aspartyl-tRNAAsp and D-tryptophanyl-tRNATrp [1]. Whereas the enzyme from the archaeon Pyrococcus abyssi is a zinc protein, the enzyme from Escherichia coli does not carry any zinc [2].
