Recent protein engineering efforts have generated artificial transcription factors that bind new target DNA sequences and enzymes that modify DNA at new target sites. Zinc-finger-based transcription factors are favored targets for design; important technological advances in their construction and numerous biotechnological applications have been reported. Other notable advances include the generation of endonucleases and recombinases with altered specificities, made by innovative combinatorial and evolutionary protein engineering strategies. An unexpectedly high tolerance to mutation in the active sites of DNA polymerases is being exploited to engineer polymerases to incorporate artificial nucleotides or to display other, nonnatural activities.

Errata:In this article, published in the August 2003 issue of Current Opinion in Biotechnology, the author’s discussion of engineering α-helical DNA-binding domains failed to note earlier reports of engineering protein–DNA interactions 1., 2., 3.. In particular, two studies reported altering the DNA-binding specificities of the Mnt repressor [1] and catabolite activator protein [2], using genetic selection methods, whereas a third described the substitution of an entire α-helix to alter the DNA-binding specificity of the 434 repressor protein [3]. The authors regret this significant oversight.
