para-Substituted(S)-phenylalanines may be obtained by treatment of the corresponding mixtures of ortho- and para-substitutedN-acetyl-(RS)-phenylalanines with Acylase I from porcine kidney. The selectivity of the enzyme may be attributed to its evolution to digest peptide derivatives of (S)-phenylalanine and (S)-tyrosine.
对位取代的(S)-苯丙氨酸可以通过用猪肾脏中的酰基转移酶I处理邻位和对位取代的N-乙酰基-(RS)-苯丙氨酸的相应混合物来获得。该酶的选择性可归因于其消化(S)-苯丙氨酸和(S)-酪氨酸的肽衍生物的进化。
