  Functional Identification and Structure Determination of Two Novel Prolidases from cog1228 in the Amidohydrolase Superfamily,

  摘要：

  Two uncharacterized enzymes from the amidohydrolase superfamily belonging to cog1228 were cloned, expressed, and purified to homogeneity. The two proteins, Sgx9260c (gi|44242006) and Sgx9260b (gi|44479596), were derived from environmental DNA samples originating from the Sargasso Sea. The catalytic function and substrate profiles for Sgx9260c and Sgx9260b were determined using a comprehensive library of dipeptides and N-acyl derivative of L-amino acids. Sgx9260c catalyzes the hydrolysis of Gly-L-Pro, L-Ala-L-Pro, and N-acyl derivatives of L-Pro. The best substrate identified to date is N-acetyl-L-Pro with a value of k(cat)/K-m of 3 x 10(5) M-1 s(-1). Sgx9260b catalyzes the hydrolysis of L-hydrophobic L-Pro dipeptides and N-acyl derivatives of L-Pro. The best substrate identified to date is N-propionyl-L-Pro with a value of k(cat)/K-m of 1 x 10(5) M-1 s(-1). Three-dimensional structures of both proteins were determined by X-ray diffraction methods (PDB codes 3MKV and 3FEQ). These proteins fold as distorted (beta/alpha)(8)-barrels with two divalent cations in the active site. The structure of Sgx9260c was also determined as a complex with the N-methylphosphonate derivative of L-Pro (PDB code 3N2C). In this structure the phosphonate moiety bridges the binuclear metal center, and one oxygen atom interacts with His-140. The a-carboxylate of the inhibitor interacts with Tyr-231. The proline side chain occupies a small substrate binding cavity formed by residues contributed from the loop that follows beta-strand 7 within the (beta/alpha)(8)-barrel. A total of 38 other proteins from cog1228 are predicted to have the same substrate profile based on conservation of the substrate binding residues. The structure of an evolutionarily related protein, Cc2672 from Caulobacter crecentus, was determined as a complex with the N-methylphosphonate derivative of L-arginine (PDB code 3MTW).

  高度亲脂性双环核苷类似物的二肽基肽酶IV依赖性水溶性前药

  摘要：

  我们提出基于二肽基肽酶IV（DPPIV / CD26）的前药方法在含羟基药物衍生物中的首次报道。特别是，我们将此策略应用于双环呋喃并嘧啶核苷类似物（BCNA）的高度亲脂性抗病毒药物家族，以改善其理化和药代动力学特性。我们的稳定性数据表明，通过纯化的DPPIV / CD26和存在于牛，鼠和人血清中的可溶性DPPIV / CD26的选择性转化，前药可有效释放母体BCNA药物。维达列汀，一种DPPIV / CD26的特异性抑制剂，在纯化的DPPIV / CD26人，鼠和牛血清的存在下能够完全阻断前药的水解。与难溶性母体药物相比，几种新颖的前药显示出水溶性的显着提高（最高超过3个数量级）。我们还证明了与小鼠母体药物相比，前药的口服生物利用度显着提高。
