Systematic Optimization of Interface Interactions Increases the Thermostability of a Multimeric Enzyme

Stapling subunits: The limited stability of multimers (see picture) is often associated with subunit dissociation. A novel procedure was applied on the basis of crystal structure analysis, sequence alignment, and single-site saturation mutagenesis to systematically identify residues in the inter-subunit interface suitable for increasing stability.
