Abstract

The translation of highly repetitive gene sequences is often associated with reduced levels of protein expression and may be prone to mutational events. In this report, we describe a modified concatemerization strategy to construct a gene with enhanced sequence diversity that encodes a highly repetitive elastinโ€like protein polymer for expression in Pichia pastoris. Specifically, degenerate oligonucleotides were used to create a monomer library, which after concatemerization yielded a genetically nonrepetitive DNA sequence that encoded identical pentapeptide repeat sequences. By limiting genetic repetition, the risk of genetic deletions, rearrangements, or premature termination errors during protein synthesis is minimized. ยฉ 2009 American Institute of Chemical Engineers Biotechnol.

## Abstract The demand for recombinant proteins for medical and industrial use is expanding rapidly and plants are now recognized as an efficient, inexpensive means of production. Although the accumulation of recombinant proteins in transgenic plants can be low, we have previously demonstrated that
