How enzymes adapt: lessons from directed evolution

How enzymes adapt: lessons from directed evolution.

Enzymes that are adapted to widely different temperature niches are being used to investigate the molecular basis of protein stability and enzyme function. However, natural evolution is complex: random noise, historical accidents and ignorance of the selection pressures at work during adaptation all cloud comparative studies. Here, we review how adaptation in the laboratory by directed evolutio...

How proteins adapt: lessons from directed evolution.

Applying artificial selection to create new proteins has allowed us to explore fundamental processes of molecular evolution. These "directed evolution" experiments have shown that proteins can readily adapt to new functions or environments via simple adaptive walks involving small numbers of mutations. With the entire "fossil record" available for detailed study, these experiments have provided...

CADEE: Computer-Aided Directed Evolution of Enzymes

The tremendous interest in enzymes as biocatalysts has led to extensive work in enzyme engineering, as well as associated methodology development. Here, a new framework for computer-aided directed evolution of enzymes (CADEE) is presented which allows a drastic reduction in the time necessary to prepare and analyze in silico semi-automated directed evolution of enzymes. A pedagogical example of...
