• Effect of the α-Methyl Substituent on Chemoselectivity in Esterase-Catalyzed Hydrolysis of <i>S</i>-Acetyl Sulfanylalkanoates

  The isomeric compounds 1 and 3, which differ only in the position of a methyl substituent, give opposite chemoselectivities in an esterase-catalyzed hydrolysis reaction. The esterase was chemoselective for the oxoester in 1, but for the thiol ester group in 3. A high enantioselectivity was observed for both 1 and 3.

  仅在甲基取代基的位置上不同的异构体化合物1和3在酯酶催化的水解反应中具有相反的化学选择性。酯酶对1中的氧代酯具有化学选择性，但对3中的硫醇酯基具有化学选择性。对1和3均观察到高对映选择性。

  MurNAc-L-amidase is one of a family of peptidoglycan hydrolases which catalyses the breakdown of bacterial peptidoglycan. Analogues of the peptidoglycan fragment MurNAc-L-Ala-γ-D-Glu containing S-thiolactic acid in place of L-alanine were synthesised as thioester substrates for this enzyme. Triphenylmethanethiol was used to develop a stereoselective synthesis of S-thiolactic acid, which was elaborated synthetically into MurNAc-dipeptide analogues. MurNAc-S-thioacetyl-N-propylamide 13 and MurNAc-S-thiolactyl-2R-alaninamide 16 were found not to be substrates for recombinant MurNAc-L-Ala amidases CwlA from Bacillus subtilis and Ply21 from bacteriophage TP21, however, turnover of tripeptide thioester S-propionylthiolactyl-γ-D-Glu-L-Lys-OMe 21 was observed using amidase Ply21. Therefore, recognition of the amino acid at position 3 of the pentapeptide sidechain appears to be important for enzymatic turnover.

  MurNAc-L-酰胺酶是催化细菌肽聚糖分解的肽聚糖水解酶家族之一。合成了一种硫酯底物，即将肽聚糖片段MurNAc-L-Ala-γ-D-Glu中的L-丙氨酸替换为S-硫乳酸的类似物。利用三苯基甲硫醇开发了S-硫乳酸的手性选择性合成方法，并进一步合成了MurNAc二肽类似物。发现MurNAc-S-硫乙酰基-N-丙基酰胺13和MurNAc-S-硫乳酰基-2R-丙氨酰胺16不是枯草芽孢杆菌重组MurNAc-L-Ala酰胺酶CwlA和噬菌体TP21的Ply21的底物，但观察到三肽硫酯S-丙酰基硫乳酰基-γ-D-Glu-L-赖氨酸甲酯21在Ply21酰胺酶的作用下发生了转氨反应。因此，对于酶促转氨反应来说，识别五肽侧链上第3位的氨基酸似乎很重要。

  Twenty one chromogenic thiopeptolide substrates were designed and synthesized as the active site probes and analyzed with each S1 site of mutant residues and enzymes of wild-type MetAP1s. The preliminary enzymatic experiments indicate that cysteine 70 or 202, at either Escherichia coli or human MetAP1, played a crucial role in the methionine hydrolysis.

  设计并合成了二十一种生色硫代peptolide底物作为活性位点探针，并用突变型残基的每个S1位点和野生型MetAP1s的酶进行了分析。初步的酶促实验表明，大肠杆菌或人MetAP1上的半胱氨酸70或202在蛋氨酸水解中起着至关重要的作用。
