Omptins (EC 3.4.23.49 protease VII protease A gene ompT proteins ompT protease protein a Pla OmpT) are a family of bacterial proteases. They are aspartate proteases which cleave peptides with the use of a water molecule. Found in the outer membrane of gram-negative enterobacteria such as Shigella flexneri Yersinia pestis Escherichia coli and Salmonella enterica. Omptins consist of a widely conserved beta barrel spanning the membrane with 5 extra-cellular loops.
