  利用配体构象选择性抑制非核糖体肽合成酶氨基酸腺苷酸化与设计的大环小分子

  摘要：

  已开发出大环氨酰基-AMP 类似物，通过模拟晶体结构中观察到的 cisoid 配体结合构象，选择性地抑制非核糖体肽合成酶氨基酸腺苷酸化结构域。相比之下，这些大环化合物不抑制氨酰-tRNA 合成酶，它们在机制上密切相关，但以不同的转体构象结合它们的配体。大环在氨基酸部分的 Cβ 和腺嘌呤环的 C8 之间包含一个两碳或三碳连接器，以及一个氨基磺酸盐代替磷酸基团。这些化合物是耶尔森菌素铁载体合成酶 HMWP2 的半胱氨酸腺苷酸化结构域活性的有效抑制剂，并且与相应的线性氨酰基-AMP 类似物不同，它们不抑制体外蛋白质翻译。

  The present invention utilizes three families of bacterial enzymes, which play a key role in mycothiol biosynthesis. The three families are bacterial cysteine:glucosaminyl inositol ligases (MshC) with catalytic ligase activity for ligation of glucosaminyl inositol and cysteine, bacterial acetyl-CoA:Cys-GlcN-Ins acetyltransferases (MshD) with catalytic activity for addition of an acetyl group to Cys-GlcN-Ins and bacterial MshA glycosyltransferase with catalytic activity for production of GlcNAc-Ins. The invention provides methods for using the mycothiol biosynthesis ligases, acetyltransferases or glycosyltransferases in drug screening assays to determine compounds that inhibit activity. The invention also provides inhibitors of the production or activity of the enzymes of mycothiol biosynthesis, and use of the inhibitors for treating microbial infection.

  本发明利用三种细菌酶家族，它们在肌硫醇生物合成中起着关键作用。这三个家族是：具有催化配体活性的细菌半胱氨酸：葡萄糖胺酰肌醇连接酶（MshC），用于连接葡萄糖胺酰肌醇和半胱氨酸；具有催化活性的细菌乙酰辅酶A：半胱氨酸-GlcN-Ins乙酰转移酶（MshD），用于向Cys-GlcN-Ins添加乙酰基；以及具有催化活性的细菌MshA糖基转移酶，用于生产GlcNAc-Ins。本发明提供了使用肌硫醇生物合成连接酶、乙酰转移酶或糖基转移酶进行药物筛选测定的方法，以确定抑制活性的化合物。本发明还提供了肌硫醇生物合成酶的产生或活性的抑制剂，并将其用于治疗微生物感染。

  There is provided a process for industrial production of non-naturally occurring proteins composed of less than 20 amino acids, wherein the proteins retain their original functions while being capable of site-specific modification or immobilization, or having new functions not found in nature in addition to the original functions of the proteins. Specifically there are provided a process for producing a functional non-naturally occurring protein having a specific amino acid type(s) replaced with a natural amino acid(s) other than the amino acid type(s), the process comprising: a) matching a nucleic acid portion having a nucleotide sequence reflecting the genotype with a protein portion that is the translation product of the nucleic acid portion; b) selecting the matched molecule obtained in step a); c) introducing mutation into the nucleic acid portion of the matched molecule obtained in step b); d) amplifying the nucleic acid portion obtained in step c); e) providing the nucleic acid portion obtained in step d) to step a), to match the nucleic acid portion with a protein portion that is the translation product of the nucleic acid portion; and f) selecting the matched molecule obtained in step e), to produce a functional non-naturally occurring protein; and a method for site-specific modification and site-immobilization of a functional non-naturally occurring protein.
