Exosortase refers to a family of integral membrane proteins that occur in Gram-negative bacteria and that recognize and cleave the carboxyl-terminal sorting signal PEP-CTERM. The name derives from a predicted role analogous to sortase despite the lack any detectable sequence homology and a strong associate of exosortase genes with exopolysaccharide or extracellular polymeric substance biosynthesis loci. Some archaea have an archaeosortase related to exosortase rather than to sortases.
