Function
Rhomboid protease is a transmembranal serine protease. The active site is buried in the lipid bilayer of cell membrane. It cleaves proteins within their transmembrane domain[1]. Rhomboids regulate many cellular processes and are involved in many human diseases. The catalytic site of rhomboids contains a hydrophilic pocket protected from the lipid bilayer. Rhomboids are specific for a single transmembranal helix proteins.
Structural highlights
The inhibitor isocoumarin binds to the GlpG catalytic residues Ser and His[2].
