Preparation of SCRATCHY Hybrid Protein Libraries

Size- and In-Frame Selection of Nucleic Acid Sequences

  • Protocol

Part of the book series: Methods in Molecular Biology™ ((MIMB,volume 231))

Abstract

SCRATCHY is a combination of the incremental truncation for the creation of hybrid enzymes (ITCHY) technology (1) and DNA shuffling (2). It generates combinatorial libraries of hybrid proteins consisting of multiple fragments from two or more parental DNA sequences with no restriction to DNA sequence identity between the original sequences (3). Such multi-crossover hybrids can be of interest to the studies of fundamental questions of protein evolution and folding, as well as to the tailoring of enzymes for therapeutic and industrial applications.
