Abstract
Novel polymers are provided which are produced by recombinant techniques. The polymers are characterized by having a small repeating sequence which provides for strands capable of associating, resulting in useful structural characteristics, where the strands are joined by turns or loops which are flexible and available for interaction with the environment. Specifically, repeating groups of naturally occurring proteins such as silk are modified by introduction of an amino-acid sequence at a site which provides for a turn between strands to provide for readily available oligopeptides capable of interacting with molecules in the environment.
