D2 hydantoinase (EC3151212) can change the D type racemates of the racemic D,L252 monosubstituted hydantoin to D2N2 carbamoylase, and the leftover L252 monosubstituted hydantoin due to never reacted with D2 hydantoinase, shown as figure 1, firstly racemizing, thus makes the D,L2 hydantoin completely changes to pure optical D2N2 carbamoylase, and then be changed to D2 amino acid.
海因酶具有底物特异性，D2海因酶(EC 3151212)可转化外消旋的D ，L252单取代海因中的D型消旋体成为D2N2氨甲酰氨基酸，剩余的L252单取代海因由于完全不被 D2海因酶所作用，如图 1所示，先进行消旋，从而使得 D ，L2海因完全转化为光学纯的 D2N2氨甲酰氨基酸，并进一步被转化为D2氨基酸。

racemization：<外>消旋化<作用>
光学异构化可分为外消旋化作用(racemization)和差向异构(epimerization). 许多酯类、酰胺类药物常受H+或OH-催化水解、这种催化作用也叫专属酸碱催化(specific acid-base catalysis)或特殊酸碱催化,此类药物的水解速度,主要由pH决定.
