ErratumEngineering proteins that bind, move, make and break DNA$Cynthia H Collins, Yohei Yokobayashi, Daisuke Umeno andFrances H ArnoldCurrent Opinion in Biotechnology 2003, 14:3713780958-1669/$ see front matter 2003 Elsevier Ltd. All rights reserved.DOI 10.1016/j.copbio.2003.10.002In this article, published in the August 2003 issue ofCurrent Opinion in Biotechnology, the authors discussionof engineering a-helical DNA-binding domains failed tonote earlier reports of engineering proteinDNA interac-tions [13]. In particular, two studies reported altering theDNA-binding specificities of the Mnt repressor [1] andcatabolite activator protein [2], using genetic selectionmethods, whereas a third described the substitution of anentire a-helix to alter the DNA-binding specificity of the434 repressor protein [3]. The authors regret this signif-icant oversight.References1. Youderian P, Vershon A, Bouvier S, Sauer RT, Susskind MM:Changing the DNA-binding specificity of a repressor.Cell 1983, 35:777-783.2.
