3.A.1.111.7
Nukacin ISK-1 bacteriocin exporter, NukT of 694 aas and 6 TMSs.  The protease domain is N-terminal, the membrane domain is central, and the ATPase domain in C-terminal. NukT and its peptidase-inactive mutant have been expressed, purified, and reconstituted into liposomes for analysis of their peptidase and ATPase activities. The ATPase activity of the NBD (C) region is required for the cysteine-type peptidase activity, and leader peptide cleavage enhances the ATPase activity (Zheng et al. 2017).
