[an analogue of the natural substrate: L-δ-(α-aminoadipoyl)-L-(cysteinyl)-D-valine] with isopenicillin N synthase (IPNS) resulted in the production of a thiocarboxylic acid, i.e. both equivalents of the dioxygen cosubstrate were utilised to oxidise a single carbon of the cysteinyl analogue. This result and others are rationalised in terms of mechanistic proposals for the first ring closure by IPNS
L -δ-(α-氨基己二酰基)-L-(3,3-二氟同型半胱氨酰)-D-缬氨酸的孵育[天然底物的类似物:L -δ-(α-氨基己二酰基)-L-(半胱氨酰)-D -缬氨酸]与异青霉素N合酶(IPNS)导致硫代羧酸的产生,即双氧共底物的两个当量都被用来氧化半胱氨酸类似物的单个碳。该结果和其他结果根据IPNS首次关闭环的机械建议进行了合理化。描述了通过3,3-二氟-β-内酰胺合成L-二氟同型半胱氨酸和相关结构。
