Mutations that substitute serine for glycine alpha 1-598 and glycine alpha 1-631 in type I procollagen. The effects on thermal unfolding of the triple helix are position-specific and demonstrate that the protein unfolds through a series of cooperative blocks.

Abstract excerpt

Cultured skin fibroblasts from two probands with lethal variants of osteogenesis imperfecta synthesized type I procollagen that was posttranslationally over-modified. Analysis of cDNAs and genomic DNAs from the two probands demonstrated that proband I had a single-base mutation that converted the codon for glycine alpha 1-631 to a codon for serine, and proband II had a single-base mutation that converted the...
