Abstract

Regulation of upp Expression in Escherichia coli by UTP-Sensitive Selection of Transcriptional Start Sites Coupled with UTP-Dependent Reiterative Transcription Anh-Hue Thi Tu and Charles L. Turnbough Jr. Department of Microbiology, University of Alabama at Birmingham, Birmingham, Alabama 35294 Volume 179, no. 21, p. 6665–6673, 1998. Page 6670, Table 1, values for strain CLT5178: For cells grown on uracil the value should be 1,800 nmol/min/mg, and for cells grown on UMP the value should be 9,850 nmol/min/mg; the fold regulation should be 5.5. Comparisons of enzyme and RNA transcript levels involving the erroneous values, which were of minor importance in the paper, need to be adjusted. Other data and conclusions, including the regulatory model, are not affected. Copyright © 1998 American Society for Microbiology
