Scissible

The differences of impressible and not impressible, figurable and not figurable, mouldable and not mouldable, scissible and not scissible, and many other passions of matter, are plebeian notions, applied unto the instruments and uses which men ordinarily practice .

The herein described article comprising a rolled-up sheet of thin soft material coated with an adhesive substance, stiffening strips of scissible material secured to opposite ends of the sheet , a plurality of suspension loops secured to one end of the sheet. and a wrapper of scissible material inclosing the body o fhte sheet with the suspension loops projecting therefrom andd serving to indicate the lines upon which the article can be severed into a plurality of individual fly catchers, weach including a portion of the sheet, one of the suspension loops, and a section of the wrapper.

The former need the presence of either a free α-NH₂ or a α-COOH group adjacent to scissible bond, whereas the latter cleaves peptide bonds of the polypeptide chain distant to the termini.

This latter Ca²⁺ site, of unknown location, is influenced by Asp residues at P3(D¹⁶⁷0 and P3' (D¹⁷²) of the scissible activation peptide bond of PC

It indicates that energy requirements for elastolysis by elastases are similar to most enzyme-catalyzed reactions, suggesting that scissible peptide bonds in elastin are accessible to these elastases.
