  Conformational Plasticity and Ligand Binding of Bacterial Monoacylglycerol Lipase

  摘要：

  Monoacylglycerol lipases (MGLs) play an important role in lipid catabolism across all kingdoms of life by catalyzing the release of free fatty acids from monoacylglycerols. The three-dimensional structures of human and a bacterial MGL were determined only recently as the first members of this lipase family. In addition to the alpha/beta-hydrolase core, they showed unexpected structural similarities even in the cap region. Nevertheless, the structural basis for substrate binding and conformational changes of MGLs is poorly understood. Here, we present a comprehensive study of five crystal structures of MGL from Bacillus sp. H257 in its free form and in complex with different substrate analogs and the natural substrate 1-lauroylglycerol. The occurrence of different conformations reveals a high degree of conformational plasticity of the cap region. We identify a specific residue, Ile-145, that might act as a gatekeeper restricting access to the binding site. Site-directed mutagenesis of Ile-145 leads to significantly reduced hydrolase activity. Bacterial MGLs in complex with 1-lauroylglycerol, myristoyl, palmitoyl, and stearoyl substrate analogs enable identification of the binding sites for the alkyl chain and the glycerol moiety of the natural ligand. They also provide snapshots of the hydrolytic reaction of a bacterial MGL at different stages. The alkyl chains are buried in a hydrophobic tunnel in an extended conformation. Binding of the glycerol moiety is mediated via Glu-156 and water molecules. Analysis of the structural features responsible for cap plasticity and the binding modes of the ligands suggests conservation of these features also in human MGL.

  萝卜硫烷的新型膦酸酯类似物：合成，体外和体内抗癌活性。

  摘要：

  设计，合成和充分表征了四十多种新颖，结构多样的萝卜硫烷膦酸酯类似物（P-ITC）的文库。评价了所有化合物在体外对Lovo和LoVo / DX结肠癌细胞系的抗增殖活性。所有化合物均显示出高抗增殖活性，与天然存在的异硫氰酸苄酯和萝卜硫烷相当或更高。对所选化合物的作用机理的评估显示了它们作为G2 / M细胞周期停滞和凋亡诱导剂的潜力。使用一组选自结肠，肺，乳腺和子宫以及正常鼠成纤维细胞的选定细胞系，对选定化合物进行了进一步的抗增殖研究。与异硫氰酸苄酯相比，对萝卜硫烷的膦酸酯类似物的体内研究显示出较低的活性。我们的研究表明，新合成的P-ITC可以用作合成具有更高抗癌活性的新型异硫氰酸酯的起点。
