Importance of the 5' untranslated region for recombinant enzyme production in isolated Bacillus subtilis 007.

The production of industrial enzymes requires an efficient expression system with a suitable host. This study investigated the isolated Bacillus subtilis 007 as a host for expressing three enzymes with potential application in the food industry. Firstly, testing the P and P promoters and the corresponding 5' untranslated regions revealed great differences in the production of the recently discovered β-galactosidase from Paenibacillus wnnyii.
