Cloning-independent expression and screening of enzymes using cell-free protein synthesis systems.

Abstract excerpt

We present a strategy for expression and screening of microbial enzymes without involving cloning procedures. Libraries of putative ω-transaminases (ω-TA) and mutated Candida antarctica lipase B (CalB) are PCR-amplified from bacterial colonies and directly expressed in an Escherichia coli-based cell-free protein synthesis system. The open nature of cell-free protein synthesis system also allows streamlined...
