Protein Engineering Strategies of DNA Gyrase B: An Approach through Hotspot Wizard Online Tool

The present study was detected hot spots and protein engineering stability, substrate specificity, tunnels and cavities as well as suitable mutability position of DNA Gyrase B protein (PDB ID: 3G7B) by using an online academic software (HotSpot Wizard, version 3.1). The prediction results were obtained in output interface for functional hot spots, stability hot spots (structural flexibility), correlated hot spots and stability hot spots (sequence consensus). only chain A attached to residues like Val at 174 and 140 position while Arg at 144 positions, respectively. The pockets and tunnels were obtained in 2 and 2 (from pocket 1), 0 and & 2 (from pocket 1) and 1 (catalytic) and no pocket was identified in which B -factor values 24.32, 15.75 and 22.47 Å2 respectively. Moreover, the amino acid residues fulfill the criterion of minimal frequency in the multiple sequence alignment. The wild type varieties were observed Val (2%), Val (38%) and Arg (47.5%). In conclusion, the pocket identification and mutability prediction of DNA Gyrase B can lead to detect structural alternation mainly in disease diagnosis and space for ligand binding pocket in new drug design for antibacterial agent. This computational prediction suggests validating experimental hotspots for DNA Gyrase B related to therapeutic efficacies and druggability assessment.
