d-Aminoacyl-tRNA deacylase (DTD) hydrolyzes d-amino acids mistakenly attached to tRNAs and, thus, has been implicated in perpetuating protein homochirality. Fifty years after the discovery of DTD, it has now been shown that its function extends beyond ‘chiral proofreading’ because it also eliminates glycine that has been erroneously coupled to tRNA^Ala.

d-酪氨酰-tRNA脱酰基酶：一项新功能

d-氨酰基-tRNA脱酰基酶（DTD）水解错误地附着在tRNA上的d-氨基酸，因此与永久性蛋白质同质性有关。发现DTD五十年后，现已证明其功能超出了“手性校对”的范围，因为它还消除了错误地与tRNA ^Ala偶联的甘氨酸。
