    Characterization of inhibitory activities and binding mode of synthetic 6′-modified methyl N-acetyl-β-lactosaminide toward rat liver CMP-d-Neu5Ac: d-galactoside-(2 → 6)-α-d-sialyltransferase
    摘要:
    6'-Deoxy (12), 6'-thio (13), and 6'-O-tetrahydropyranosyl (14) analogues of methyl N-acetyl-beta-lactosaminide (3), were synthesized from lactose. NOE experiments proved that they adopt the same conformation as that of 3. Inhibition studies using these synthetic analogues, including the disulfide dimer 15, toward (2 --> 6)-alpha-sialyltransferase (EC 2.4.99.1) revealed that the 6'-deoxy analogue 12 had remarkable inhibitory activity as the first acceptor-analogue inhibitor for this enzyme. It is noteworthy that the disulfide 15 also behaves as an inhibitor. The results indicated that chemical modification at the 6'-position of 3 did not cause much decrease in the binding affinity to the sialyltransferase. Further, a novel possibility that the acceptor and the acceptor-analogue inhibitor can bind simultaneously to the sialyltransferase was proposed based on the inhibition studies with 12 and CMP.

    摘要:
    通过使用弱亲和色谱(WAC),NMR光谱学和分子模拟相结合的方法研究蛋清蛋白溶菌酶(HEWL)与市售和化学合成的碳水化合物配体之间的相互作用,我们报告了新的亲和力数据以及HEWL蛋白的详细结合模型。配位体的平衡解离常数既可以通过WAC获得,也可以通过NMR光谱获得,两者相吻合。使用1 H饱和转移差(STD)效应通过NMR光谱推导了溶液中的两种HEWL-二糖复合物的结构,并转移了1 H,1H-NOESY实验,弛豫矩阵计算,分子对接和分子动力学模拟。在溶液中两个二糖β- d -Gal p - (1→4)-β- d -Glc p NAC-OME和β- d -Glc p NAc-(1→4)-β- d -Glc p NAc- OMe在两个糖残基之间的糖苷键处以顺式构象结合HEWL的B和C位点。分子间氢键键合和CH /π相互作用以糖-蛋白相互作用的特征形式形成了蛋白-配体复合物的基础。显式的分子动力学
