In vitro evolution of a hyperstable Gbeta1 variant.

Abstract excerpt

An in-vitro selection strategy was used to obtain strongly stabilized variants of the beta1 domain of protein G (Gbeta1). In a two-step approach, first candidate positions with a high potential for stabilization were identified in Gbeta1 libraries that were created by error-prone PCR, and then, after randomization of these positions by saturation mutagenesis, strongly stabilized variants were selected. For both...
