WebJul 27, 2011 · The reactive center loop (RCL) extends out from the body of the protein and directs binding to the target protease. The protease cleaves the serpin at the reactive site within the RCL, establishing a covalent linkage between the serpin reactive site and the protease. The resulting inactive serpin-protease complex is highly stable (By similarity). Webserpin in its native, active conformation has a flexible reactive center loop (RCL) located near the C terminus and protruding from the main body of the protein as a bait. The proteinase recognizes a specific peptide bond (P 1-P 19) in the RCL, and a Michaelis-type encounter complex is formed between enzyme and inhibitor.
