Abstract

Directed evolution was used to improve the activity of JamB, a membrane-bound bifunctional desaturase/acetylenase. To quickly assess the protein engineering outcomes, we developed a new platform for quantifying extracellular alkyne-tagged metabolites through a fluorogenic click reaction. Random mutagenesis yielded the best JamB variant with ∼20-fold increased activity in E. coli. [ABSTRACT FROM AUTHOR]
