Recombinant Expression and Purification of Large Bacterial Multienzyme Assemblies for Biosynthetic Processes. | LitMetric

AI Article Synopsis

Article Abstract

Many biosynthetic transformations have strict spatial and temporal requirements that necessitate the physical association of multiple enzymes for proper function. Here, we describe protocols for obtaining large multienzyme assemblies (>500 kDa) by recombinant expression in Escherichia coli. We focus on assemblies from stand-alone enzymes joined by intermolecular forces rather than multiple catalytic domains from a single polypeptide chain. Details are given for strategies to optimize protein expression and to design a multi-affinity tag purification scheme for large multienzyme assemblies. These insights are drawn from our study of bacterial hydrocarbon biosynthesis.
