We have studied the refolding and thermal denaturation of hen egg white lysozyme in a wide range of pH values (from 1.5 to 9.4) using stopped-flow circular dichroism (CD) and differential scanning calorimetry (DSC). A linear correlation was found between the thermal denaturation temperature (T(m)) and the logarithm of the refolding rate of the slow folding(More)
The structure of acetamidase/formamidase (Amds/Fmds) from the archaeon Thermoanaerobacter tengcongensis has been determined by X-ray diffraction analysis using MAD data in a crystal of space group P2₁, with unit-cell parameters a = 41.23 (3), b = 152.88 (6), c = 100.26 (7) Å, β = 99.49 (3) ° and been refined to a crystallographic R-factor of 17.4% and(More)
We have studied the structural features of toxic chemicals from the RTECS database associated with specific toxicity. The frameworks, functional groups, and structure patterns of molecules are taken into account. Potential active frameworks, groups, and structure patterns for specific toxicity are gained by computational chemistry approaches. These(More)
The putative metal-dependent hydrolase gene TTE1006 from Thermoanaerobacter tengcongensis strain MB4T (T = type strain; Genbank accession No. AE008691) was heterologously expressed in Escherichia coli. The 205-amino-acid gene product was purified and crystallized. The crystal used for data collection belongs to space group P2(1), with unit-cell parameters a(More)
No crystal structures are yet available for homologues of a predicted acetamidase/formamidase (Amds/Fmds) from the archaeon Thermoanaerobacter tengcongensis. The Amds/Fmds gene was cloned and expressed as a soluble protein in Escherichia coli. Native Amds/Fmds and its SeMet-substituted form were purified and crystallized by vapour diffusion in hanging drops(More)
Alpha-insect scorpion toxins are a distinct group of scorpion neurotoxins for which no crystal structures are yet available. A novel alpha-insect toxin named BmKalphaIT1 from the scorpion Buthus martensii Karsch (BmK) has been expressed as an inclusion body in Escherichia coli and purified by chromatography after renaturation. Recombinant BmKalphaIT1(More)
Dicycloplatin is a new generation supramolecular platinum-containing anti-cancer drug. Due to its structure, it is difficult to differentiate dicycloplatin from physical mixtures of carboplatin and cyclobutane dicarboxylate, and confounding results may arise during drug characterization. To solve this problem, this study aims to provide a reliable and(More)
