Gather some information on your gene. Probably in literature survey you can find the vector for your gene to be cloned. If not finding then try in NEB cutter to short out the suitable vector. You have to 1st choose two suitable restriction enzymes to cut the genes from Bacillus plasmid. The same enzymes should also be used to cut the vector at suitable site. Then ligase the gene into the vector. Transform the vector into E. coli compitant cells. Then amplify the plasmid in E. coli. harvest the plasmids from E. coli. You must have a antibiotic resistance selection in the plasmid. The activity of expressed gene you can check in two ways. Design the primers for your gene and do PCR with the plasmid after the gene is amplified in E coli or use a tagged vector with fluorescence marker so that the expression you can check under microscope. For the protocols simple read and follow Sambooks text books.
