摘要

Microbial redox reactions of inorganic sulphur compounds play vital role for recycling of sulphur to maintain environmental sulphur balance. These important reactions are carried out by enzyme system encoded by sox operon. Central player of sulphur oxidation process is SoxY-Z protein complex. Thermophilic betaproteobacterium- Hydrogenophilus thermoluteolus, oxidizes sulphur compounds including thiosulfate with the help of proteins encoded by sox operon. Protein SoxF having sulfide dehydrogenase activity has the ability to reactivate the inactivated SoxY-Z complex. Till date no structural details are available for SoxF protein from H. thermoluteolus. In present work, homology modeling has been used to build 3D structures of SoxY, SoxZ and SoxF of H. thermoluteolus. 3D structure of SoxY-Z-F complex was obtained by ClusPro2.0. Amino acid residues responsible for proteinprotein interaction were identified. Interactions in SoxY-Z-F were found to be mediated through hydrogen bonding. Probable biophysical mechanism of the interactions of SoxF with SoxY-Z complex has been identified.

Thermoluteolus的SOXF蛋白质。在目前的工作中,同源性建模已被用于构建H. Thermoluteolus的Soxy,Soxz和SoxF的3D结构。 CLUSPRO2.0获得了SOXY-Z-F复合物的3D结构。鉴定了负责蛋白质蛋白相互作用的氨基酸残基。发现SOxy-Z-F的相互作用通过氢键粘接来介导。已经鉴定了SOxF与SOxy-Z综合体的相互作用的可能生物物理机制。
