Schematic representation of Natrialba magadii ATCC 43099 proteolytic systems. The major proteases and protease inhibitor proteins predicted from the analyses of Nab. magadii genome are depicted. NSP (Nab. magadii serine protease), NMP (Nab. magadii metalloprotease), NSI (Nab. magadii subtilisin inhibitor), NEP (Nab. magadii extracellular protease), and LonB have been described in the literature. SPs, Signal peptidases; I-CLiPs, Intramembrane-Cleaving Proteases; SPPs, Signal peptide peptidases; S2Ps, Site-2 proteases; HtrA, serine protease HtrA; HtpX, putative membrane-bound zinc metalloprotease; TET, Tetrahedral aminopeptidase (Peptidase M42 family); MlrC-like protein, Microcystin LR degradation protein; PEBP, Phosphatidylethanolamine-binding protein (putative protease inhibitor); TM, Transmembrane domain; Tat, Twin arginine translocation pathway.
