Nocardiopsis alba Protease A, or NAPase, is an acid-resistant homolog of alpha-lytic protease. As such, NAPase and alp are both kinetically stable proteases, meaning it is the large barrier to unfolding that keeps this protease in its folded, active state. This is different from most other proteins, which stay in their folded, or native, state because of the energy difference between their native and unfolded states, with the native state being lower in energy.
The NAPase molecule provided shows two NAPase molecules that are mirror images, so here is just . One of the major features of NAPase, as well as alpha-lytic protease, is that each protease has two domains, an N domain and a C domain. In this , one can see that the N domain (red, orange, yellow) is connected covalently through the protein to the C domain (green, blue, violet), and that there are multiple stabilizing interactions between the domains.
