Serine protease (specific type not given; likely needs refinement with UniProt or original PDB record)

Serine proteases are a major class of enzymes characterized by a serine residue at their active site that participates directly in the hydrolysis of peptide bonds. They play key roles in numerous physiological processes including digestion, immune response, blood coagulation, and inflammation. The PDB entry 1O3J details the structural complexity of hydrogen bond networks mediating the binding of small molecule inhibitors to the active site of such proteases, informing the design of selective drugs targeting this enzyme class[1].
