WebIn this model, the native reactive center is part of an exposed loop, also called the strained loop 6–8. Upon cleavage, this loop moves or “snaps back”, becoming one of the central strands in a major β -sheet structure (β-sheet A). This transformation is accompanied by a large increase in thermal stability 9–12. Keywords Plasminogen Activator Webminal end of the cleaved reactive center loop has been inserted into the major βsheet (βsheet A), forming a new βstrand [5]. A similar loop insertion is believed to occur in the formation of the inhibited complex [3]. PAI-1 is a prototype among serpins due to its ability to convert spon-taneously, without cleavage, to an inactive conformation
