Abstract

Using phage display mutagenesis, high affinity variants of RNase S-peptide were produced that bind to RNase S-protein over 100-fold more tightly than the wild type S-peptide. The S-peptide: S-protein interface was further characterized using “biased” phage display libraries, where each targeted residue was …

Biosynthetic phage display: a novel protein engineering tool combining chemical and genetic diversity

Dwyer MA, Lu W, Dwyer JJ, Kossiakoff AA

Chem. Biol. 2000 Apr;7(4):263-74

PMID: 10780926

Abstract

BACKGROUND: Molecular diversity in nature is developed through a combination of genetic and chemical elements. We have developed a method that permits selective manipulation of both these elements in one protein engineering tool. It combines the ability to introduce non-natural …
