Abstract
Rieske non-heme iron oxygenases (ROs) possess the ability to catalyze a wide range of reactions. Their ability to degrade aromatic compounds is a unique characteristic and makes ROs interesting for a variety of potential applications. However, purified ROs can be challenging to work with due to low stability and long, complex electron transport chains. Whole cell biocatalysis represents a quick and reliable method for characterizing the activity of ROs and harnessing their metabolic potential. In this protocol, we outline a step-by-step protocol for the overexpression of ROs for whole cell biocatalysis and characterization. We have utilized a caffeine-degrading, N-demethylation system, expressing the RO genes ndmA and ndmD, as an example of this method.
期刊介绍：
The critically acclaimed laboratory standard for almost 50 years, Methods in Enzymology is one of the most highly respected publications in the field of biochemistry. Each volume is eagerly awaited, frequently consulted, and praised by researchers and reviewers alike. Now with over 500 volumes the series contains much material still relevant today and is truly an essential publication for researchers in all fields of life sciences, including microbiology, biochemistry, cancer research and genetics-just to name a few. Five of the 2013 Nobel Laureates have edited or contributed to volumes of MIE.
