self-cleavage is required for secretion of the mature extracellular enzyme form, cleavage targets contain a proline-rich consensus recognition sequence, Pro-Pro-Ser-Pro, residing in the variable linker region that connects the protease and translocator domains, the precise amino acid sequence of the intervening region, between mature IgA1 protease and the beta-core translocator domain, influences the efficiency of autoproteolytic processing |
