Search for mutations affecting protein structure in children of atomic bomb survivors: preliminary report.

abstract：:Spontaneous cross-linking in vitro, during incubation of purified collagen in nonstriated and native type fibrils, was studied to elucidate the relationship between intra and intermolecular cross-links. In nonbanded fibrils, the aldol condensation products of two allysyl residues, previously shown to constitute the in...
