Elastin as a rubber

open access: yesBiopolymers, 1977
AbstractThe thermoelastic behavior of water solvated elastin has been investigated in simple tension, in the temperature range 0–70°C. Specimens purified from both the ox ligamentum nuchae and pig thoracic aorta have been studied. Force data obtained by cycling the temperature for various constant specimen lengths display a separated variable ...

Rubber oxygenases [PDF]

open access: yesApplied Microbiology and Biotechnology, 2018
Natural rubber (NR), poly(cis-1,4-isoprene), is used in an industrial scale for more than 100 years. Most of the NR-derived materials are released to the environment as waste or by abrasion of small particles from our tires. Furthermore, compounds with isoprene units in their molecular structures are part of many biomolecules such as terpenoids and ...
