Abstract excerpt
The cause of the Ehlers-Danlos syndrome Type VII (EDS VII) is considered to be defective removal of the amino-terminal propeptide (N-propeptide) of Type I procollagen due to deficiency of procollagen N-proteinase, the enzyme responsible for the normal proteolytic excision of this precursor-specific domain. Molecules retaining the N-propeptide (pN-collagen molecules) are thought to cause defective fibrillogenesis...
