The cyanogen bromide-resistant proteins of lamprey cartilage are biochemically related to the mammalian elastic protein, elastin. This study investigates their mechanical properties and enquires whether, like elastin, long-range elasticity arises in them from a combination of entropic and hydrophobic mechanisms.
