Webthe whole of the reactive center loop (from P15 to approxi-mately P3) into b-sheet A as strand 4 (12, 13), b-sheet A of antithrombin must reopen at the critical point of the mecha-nism to allow re-insertion of residues P15 and P14, as well as the remainder of the reactive center loop, with the proteinase covalently bound to the P1 residue. WebThe 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 carboxyl group of the serpin reactive site and the serine hydroxyl of the protease.
