THE STRUCTURE OF THE SYNTHETIC a-POLYPEPTIDES
THE classic work of Astbury [l] has shown that structurally the fibrous proteins fall into two main groups : the keratin-myosinepidermin-fibrinogen group, known for short as km-o-f, and the collagens. The distinction between them is displayed most clearly by their wide-angle X-ray diffraction patterns. These also show that the k-m-e-f group can exist in two forms, known as CC and /l, which unde...
متن کاملEffect of membrane splitting on transmembrane polypeptides
We investigated the effect of membrane splitting on the primary structure of human erythrocyte membrane polypeptides. Monolayers of intact, chemically unmodified cells were freeze-fractured and examined by one-dimensional SDS PAGE. Silver-stained gels revealed all major polypeptides that stain with Coomassie Blue as well as all bands that stain with periodic acid Schiff's reagent. Both nonglyco...
متن کاملMechanochemical coupling in synthetic polypeptides by modulation of an inverse temperature transition.
For the polypentapeptide of elastin, (L-Val-L-Pro-Gly-L-Val-Gly)n, and appropriate analogs when suitably cross-linked, it has been previously demonstrated that development of elastomeric force at fixed length and length changes at fixed load occur as the result of an inverse temperature transition, with the temperature of the transition being inversely dependent on the hydrophobicity of the pol...
متن کاملSome properties of the bacitracin polypeptides.
Newton & Abraham (1950) found that crude bacitracin could be resolved into a series of similar polypeptides by counter-current distribution between solvents. Better resolution and larger amounts ofthe products have now been obtained by using a greater number of transfers and starting with more concentrated solutions than were used in the earlier experiments. It has been possible, by a single di...
