The emergence of tuberculosis is at the peak; therefore to station it at its lower level we hereby try bioinformatics approach against [] pathogenesis. Rv3906c is a conserved hypothetical gene of and contains many GTP binding protein motif DXXG which demonstrate that this gene might be processed in a GTP binding or in GTP hydrolyzing manner. This gene shows interaction with its adjacent genes as well as which is a polymerase and localized in the extracellular region and found to be a soluble protein. Rv3906c has binding pockets for calcium atom at various positions which prove that calcium might have some role during the process of this gene. GTP binding protein motif DXXG is present in various positions and calcium binds at this site with a C-score of 0.25. Mutational analysis on this motif shows the large decrease of stability after mutation of aspartate residue with glycine. Stress conditions like pH and temperature also change stability of the protein. A decrease in stability at this position might play a role in inhibition of survival of the pathogen. These computational studies of this gene might be a successful step towards drug development against tuberculosis.
结核病的出现正处于高峰期；因此，为了将其控制在较低水平，我们在此尝试采用生物信息学方法来对抗[]发病机制。Rv3906c是一个保守的假设基因，含有许多GTP结合蛋白基序DXXG，这表明该基因可能以GTP结合或GTP水解的方式进行加工。该基因与其相邻基因以及作为聚合酶并定位于细胞外区域且被发现是一种可溶性蛋白的[]显示出相互作用。Rv3906c在不同位置有钙原子的结合口袋，这证明钙在该基因的过程中可能起一定作用。GTP结合蛋白基序DXXG存在于不同位置，钙以0.25的C分数结合于此位点。对该基序的突变分析表明，天冬氨酸残基被甘氨酸取代后稳定性大幅下降。pH和温度等应激条件也会改变蛋白质的稳定性。该位置稳定性的降低可能在抑制病原体存活中起作用。对该基因的这些计算研究可能是抗结核药物开发的成功一步。
