| Abstract: | A 73-residue tryptic fragment from chick aortic tropoelastin has been sequenced by solid state methods. This is a new structure not previously described in any tropoelastins and may be unique for avians. It contains a G V P tripeptide repeat, giving it a primary structure like that of collagen. This may explain some of the collagen-like properties observed in elastin, particularly collagenase susceptibility and the presence of hydroxyproline. |
