Abstract

Cleavage of ovalbumin and angiotensinogen at sites homologous to the reactive centre loop of alpha 1-antitrypsin is not accompanied by the increase in heat-stability associated with the transition from the native stressed (S) structure to a cleaved relaxed (R) form that is typical of other serpins. Failure to undergo the S-R change in ovalbumin is not due to phosphorylation of Ser-344 near the sites of cleavage on the loop. The suggested explanation is the unique presence of bulky side chains at the P10-P12 site in ovalbumin and angiotensinogen.
