- Abstract
To date, there have been no or just a few reports of successful cloning and expression to create biologically active ocins or bacteriocins. Cloning, expression, and production of class I ocins are problematic because of their structural arrangements, coordinated functions, size, and posttranslational modifications. Mass synthesis of these molecules is necessary for commercialization and to restrict the excessive use of conventional antibiotics, which encourages the development of antibiotic-resistant bacteria. In the case of class III ocins, there are no reports of obtaining biological active proteins to date. Being able to obtain biologically active proteins requires an understanding of mechanistic features due to their expanding importance and broad spectrum of activity. As a result, we intend to clone and express the class III type. The class I types that are devoid of posttranslational modifications were transformed into class III through fusion. Therefore, this construct resembles a class III type ocin. With the exception of Zoocin, expression of the proteins was found to be physiologically ineffective after cloning. But, few cell morphological changes such as elongation, aggregation, and the formation of terminal hyphae were observed. However, it was discovered that the target indicator had been altered to Vibrio spp. in a few. All the three ocins were subjected to in-silico structure prediction/analysis. Finally, we confirm the existence of unidentified additional intrinsic factors for successful expression to obtain biologically active protein.
