DNA helicases of the RecQ family are distributed among most organisms and are thought to play important roles in various aspects of DNA metabolism. The founding member of the family, RecQ of Escherichia coli, was identified in a study aimed at clarifying the mechanism of thymineless death, a phenomenon underlying the mechanism for the cytotoxicity of the anticancer drug 5-fluorouracil. The present article is concerned solely with E. coli RecQ and tries to offer an integrated picture of the past and present of its study. Finally a brief discussion is given on how RecQ is involved in thymineless death. (C) 2005 Elsevier B.V. All rights reserved.
