Emergence of diverse biochemical activities in evolutionarily conserved structural scaffolds of proteins

Vivek Anantharaman et al. Curr Opin Chem Biol. 2003 Feb.

Abstract

Comparative analysis of numerous protein structures that have become available in the past few years, combined with genome comparison, has yielded new insights into the evolution of enzymes and their functions. In addition to the well-known diversification of substrate specificities, enzymes with several widespread catalytic folds, particularly the TIM barrel, the RRM-like domain and the double-stranded beta-helix (cupin) domain, have been extensively explored in 'reaction space', resulting in the evolution of numerous, diverse catalytic activities supported by the same structural scaffold. Common protein folds differ widely in the diversity of catalyzed reactions. The biochemical plasticity of a fold seems to hinge on the presence of a generic, symmetrical substrate-binding pocket as opposed to highly specialized binding sites.
