The intramembrane rhomboid proteases are of particular interest due to their ability to hydrolyze a substrate peptide bond at the active site which is buried within the membrane. The high-resolution structure of the E. coli rhomboid protease GlpG revealed the catalytic dyad Ser201/His254, which is surrounded by a protein matrix and connected to bulk water via a narrow water channel. Although multiple crystal structures have been solved for GlpG, its catalytic mechanism is not clearly understood.
