Peptides comprising repetitive units of amino acids and DNA sequences encoding the same
First Claim
1. A recombinantly produced protein of from 30 kDal to 250 kDal comprising at least 50 number percent of amino acids of at least one naturally occurring repeating unit of a naturally occurring structural protein, wherein said repeating units are from 4 to 20 amino acids in length and wherein each of said repeating units which comprise said at least 50 number percent of the amino acids of said protein are tandemly repeated at least once in the protein.

Abstract
Polypeptides comprising repetitive units of amino acids, as well as synthetic genes encoding the subject polypeptides are provided. The subject polypeptides are characterized by comprising repetitive units of amino acids, where the repetitive units are present in naturally occurring proteins, particularly naturally occurring structural proteins. The subject polypeptides find use in a variety of applications, such as structural components of prosthetic devices, synthetic fibers, and the like.
