Location of highly variable loop region in the 3CLpro of HKU1 (3D23). Colouring of backbone elements by B-factor indicates the presence of a highly variable loop from residues Ser46 to Asp53. This variable loop region may be responsible for the spike in DOPE score for 3D23, for which OC43 3CLpro has assumed a more stable conformation.
