  • From Genome to Proteome to Elucidation of Reactions for All Eleven Known Lytic Transglycosylases from <i>Pseudomonas aeruginosa</i>
    作者:Mijoon Lee、Dusan Hesek、David A. Dik、Jennifer Fishovitz、Elena Lastochkin、Bill Boggess、Jed F. Fisher、Shahriar Mobashery

    An enzyme superfamily, the lytic transglycosylases (LTs), occupies the space between the two membranes of Gram‐negative bacteria. LTs catalyze the non‐hydrolytic cleavage of the bacterial peptidoglycan cell‐wall polymer. This reaction is central to the growth of the cell wall, for excavating the cell wall for protein insertion, and for monitoring the cell wall so as to initiate resistance responses
    酶超家族,即溶菌转糖基酶(LTs),占据了革兰氏阴性细菌两膜之间的空间。LTs催化细菌肽聚糖细胞壁聚合物的非解裂解。该反应对于细胞壁的生长至关重要,可用于挖掘细胞壁以插入蛋白质,并用于监测细胞壁,从而引发对具有细胞壁作用的抗生素的抗药性反应。凶恶的革兰氏阴性病菌绿假单胞菌编码11个LT。除少数例外,它们的底物和功能未知。每个绿假单胞菌LT表达为可溶性蛋白,并用一组底物(天然底物的简单和复杂模拟物)进行评估。31种不同的产品在底物识别,催化活性以及相对的内溶或内溶能力方面对这些LT进行了区分。这些特性是将LT作为催化剂和抗生素靶标的基础。

    that the incorporation of an anhydromuramyl-containing glycosyl acceptor by TGase into the growing PG may effectively inhibit PG elongation. To explore this possibility, we synthesized 4-O-(N-acetyl-β-d-glucosaminyl)-1,6-anhydro-N-acetyl-β-d-muramyl-l-Ala-γ-d-Glu-l-Lys-d-Ala-d-Ala, 1, within 15 steps, and demonstrated that this anhydromuropeptide and its analogue lacking the peptide, 1-deAA, were both
    肽聚糖(PG)是细菌中一种重要的外骨骼聚合物,是众所周知的抗生素靶标。 PG 聚合需要细菌转糖基酶 (TGase) 的作用,它将传入的糖基受体与供体偶联。干扰 TGase 活性会中断 PG 组装。现有的TGase抑制剂如莫诺霉素和Lipid II类似物总是占据TGase活性位点;其他干扰 PG 适当伸长的策略尚未得到广泛利用。受到细菌中标记 PG 链末端的天然 1,6-脱-MurNAc 末端的启发,我们假设 TGase 将含有脱胞壁酰基的糖基受体掺入生长的 PG 中可能会有效抑制 PG 延伸。为了探索这种可能性,我们合成了 4- O -( N -乙酰基-β- d -葡萄糖胺基)-1,6-anHydro- N -乙酰基-β- d -胞壁酰- l -Ala-γ- d -Glu- l -Lys -d -Ala- d -Ala, 1 ,在 15 个步骤内,并证明这种脱壁肽及其缺乏肽的类似物1-deAA在体外均被细菌

  • Reactions of the Three AmpD Enzymes of <i>Pseudomonas aeruginosa</i>
    作者:Weilie Zhang、Mijoon Lee、Dusan Hesek、Elena Lastochkin、Bill Boggess、Shahriar Mobashery

    A group of Gram-negative bacteria, including the problematic pathogen Pseudomonas aeruginosa, has linked the steps in cell-wall recycling with the ability to manifest resistance to beta-lactam antibiotics. A key step at the crossroads of the two events is performed by the protease AmpD, which hydrolyzes the peptide in the metabolite that influences these events. In contrast to other organisms that harbor this elaborate system, the genomic sequences of P. aeruginosa reveal it to have three paralogous genes for this protease, designated as ampD, ampDh2, and ampDh3. The recombinant gene products were purified to homogeneity, and their functions were assessed by the use of synthetic samples of three bacterial metabolites in cell-wall recycling and of three surrogates of cell-wall peptidoglycan. The results unequivocally identify AmpD as the bona fide recycling enzyme and AmpDh2 and AmpDh3 as enzymes involved in turnover of the bacterial cell wall itself. These findings define for the first time the events mediated by these three enzymes that lead to turnover of a key cell-wall recycling metabolite as well as the cell wall itself in its maturation.
