The active site is buried in the lipid bilayer of cell membrane. It cleaves proteins within their transmembrane domain. 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 covalently binds to the GlpG catalytic residues Ser and His (in deepskyblue). Whole active site. Water molecules shown as red spheres.
