To identify specific target protein sites in Bacillus subtilis for docking studies, you will need to consider the protein of interest. Bacillus subtilis is a bacterium with a wide range of proteins and functions, so the specific target sites will depend on the protein you are studying.
Ma'am, you can try GyraseB (PDB ID-6F86) and Tyrosyl-tRNA synthetase (PDB ID-1JIJ). These proteins are extensively used for studying antimicrobial properties of drug candidates as the structure of these proteins is conserved in nature and doesn't vary from species to species.
it would be better to use that protein, which is essential for bacterial survival and is absent in humans. The protein also has very less possibility to be mutated... as suggested, Samik Gyrase B would be the better option because in humans its alternative protein is topoisomerase and this is an essential enzyme for bacterial survival... you may go through this article...

Bacillus subtilis is a gram-positive bacterium commonly used as a model organism for research and biotechnological applications. It possesses several protein targets that can be studied using molecular docking. Here are some prominent protein sites in Bacillus subtilis that have been explored in docking studies
DNA Gyrase: DNA gyrase is a type II topoisomerase enzyme involved in DNA replication, recombination, and repair. It is a potential target for antibacterial agents. The GyrA and GyrB subunits of DNA gyrase can be targeted for docking studies.
RNA Polymerase Bacillus subtilis. The binding site of rifampicin, an antibiotic that inhibits RNA polymerase, has been widely studied and can be used for docking investigations.
Proteases: various proteases involved in protein degradation and processing inhibitors or other compounds can be docked into the active sites of these enzymes to study their inhibition mechanisms.
Lipases: Bacillus subtilis secretes lipases that can be targeted for docking studies. The active site of lipases can be explored for potential inhibitors or substrates.
: Bacillus subtilis possesses enzymes involved in cell wall biosynthesis, such as peptidoglycan synthesis enzymes and cell wall hydrolases. These enzymes can be targeted for docking to understand their interaction with inhibitors or substrates.
Antibiotic Resistance Proteins: Bacillus subtilis may harbor proteins involved in antibiotic resistance, such as efflux pumps or enzymes that modify antibiotics. These proteins can be studied for their interaction with known antibiotics or potential inhibitors.
It is important to note that the choice of protein targets for docking studies depends on the specific research question or objective. The mentioned proteins represent a subset of potential targets in Bacillus subtilis, and researchers may focus on other proteins based on their specific interests.
