    • The present invention describes a process for the production of an N-α-amino-hydroxyphenylacetyl or an N-α-aminophenylacetyl β-lactam antibiotic comprising an IPNS-catalysed conversion of a precursor tripeptide hydroxyphenylglycyl-cysteinyl- valine (HpgCV) or phenylglycyl-cysteinyl-valine (PgCV), respectively, to the N- hydroxyphenylglycyl or the N-phenylglycyl β-lactam antibiotic, respectively. The tripeptide HpgCV or the tripeptide PgCV may further be prepared by contacting the amino acids hydroxyphenylglycine (Hpg) or phenylglycine (Pg), cystein (C) and valine (V) with a non-ribosomal peptide synthetase (NRPS) to effect formation of the tripeptide HpgCV or the tripeptide PgCV, the NRPS comprising a first module M1 specific for Hpg or Pg, a second module M2 specific for C and a third module M3 specific for V. An IPNS is further provided having an improved activity in this conversion, as well as an NRPS catalysing the formation of the tripeptides. Also a host cell is provided capable of fermentatively producing β-lactam antibiotics with N-α-amino-hydroxyphenylacetyl or an N-α-aminophenylacetyl side chains.
    • 本发明描述了用于生产N-α-氨基 - 羟基苯基乙酰基或N-α-氨基苯基乙酰基β-内酰胺抗生素的方法,其包含IPNS-催化的前体三肽羟基苯基甘氨酰 - 半胱氨酰 - 缬氨酸(HpgCV)或苯基甘氨酰 - 半胱氨酰 - 缬氨酸(PgCV)分别与N-羟基苯基甘氨酰基或N-苯基甘氨酰基β-内酰胺抗生素接触。 三肽HpgCV或三肽PgCV还可以通过使氨基酸羟苯甘氨酸(Hpg)或苯基甘氨酸(Pg),半胱氨酸(C)和缬氨酸(V)与非核糖体肽合成酶(NRPS)接触以制备 三肽HpgCV或三肽PgCV,NRPS包含特异于Hpg或Pg的第一模块M1,特异于C的第二模块M2和特异于V的第三模块M3。进一步提供具有改进的活性的IPNS, 以及催化三肽形成的NRPS。 还提供了能够用N-α-氨基 - 羟基苯基乙酰基或N-α-氨基苯基乙酰基侧链发酵产生β-内酰胺抗生素的宿主细胞。
