Function

[RSEP_ECOLI] A site-2 regulated intramembrane protease (S2P) that cleaves the peptide bond between 'Ala-108' and 'Cys-109' in the transmembrane region of RseA. Part of a regulated intramembrane proteolysis (RIP) cascade. Acts on DegS-cleaved RseA to release the cytoplasmic domain of RseA, residue "Val-148" of RseA may be required for this. This provides the cell with sigma-E (RpoE) activity through the proteolysis of RseA. Can also cleave sequences in transmembrane regions of other proteins (such as LacY) as well as liberated signal peptides of beta-lactamase, OmpF, LivK, SecM, PhoA, LivJ, OmpC, Lpp and TorA, probably within the membrane.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7]

Publication Abstract from PubMed

Regulated intramembrane proteolysis (RIP) by the Site-2 protease (S2P) results in the release of a transmembrane signaling protein. Curiously, however, S2P cleavage must be preceded by the action of the Site-1 protease (S1P). To decipher the underlying mechanism, we reconstituted sequential, in vitro cleavages of the Escherichia coli transmembrane protein RseA by DegS (S1P) and RseP (S2P). After DegS cleavage, the newly exposed carboxyl-terminal residue Val-148 of RseA plays an essential role for RseP cleavage, and its mutation to charged or dissimilar amino acids crippled the Site-2 cleavage. By contrast, the identity of residues 146 and 147 of RseA has no impact on Site-2 cleavage. These results explain why Site-1 cleavage must precede Site-2 cleavage. Structural analysis reveals that the putative peptide-binding groove in the second, but not the first, PDZ domain of RseP is poised for binding to a single hydrophobic amino acid. These observations suggest that after DegS cleavage, the newly exposed carboxyl terminus of RseA may facilitate Site-2 cleavage through direct interaction with the PDZ domain.

Cleavage of RseA by RseP requires a carboxyl-terminal hydrophobic amino acid following DegS cleavage.,Li X, Wang B, Feng L, Kang H, Qi Y, Wang J, Shi Y Proc Natl Acad Sci U S A. 2009 Aug 17. PMID:19706448^[8]
