요약 | Inteins are protein elements that autocatalytically excise themselves from a host protein in a process called protein splicing. The two flanking sequences of the host protein, called the N- and C-exteins, are subsequently ligated with a native p |
요약 | During this process, the intein breaks two peptide bonds and forms a third. Taking advantage of the intein's ability to catalyze these reactions, both within the natural host as well as in vitro for biotechnological applications, provides an att |
요약 | Our work focuses on two of the three inteins found in the human pathogen Mycobacterium tuberculosis (Mtu), RecA and SufB. The intein-interrupted proteins are important for the viability of Mtu. Preventing intein excision, and thus the formation |
요약 | Turning to methods of control for in vitro applications, we introduced a mutation in Mtu RecA that causes the intein to spontaneously form a thiazoline ring at the N-terminal splicing junction. While present, the thiazoline ring prevents any fur |
요약 | The final aspect of our work is based on the intriguing hypothesis that inteins are not simply parasitic elements, but offer a beneficial protein-level control of host protein function. We demonstrated that Mtu SufB activity is inhibited in vivo |
요약 | Overall, this work investigates strategies for controlling inteins in the realms of drug development, protein purification, and host regulation and stress response. |
