Abstract

The Escherichia coli gene murZ was recently shown to encode UDP-N-acetylglucosamine enolpyruvyl transferase, which catalyzes the first committed step of peptidoglycan biosynthesis (J. L. Marquardt, D. A. Siegele, R. Kolter, and C. T. Walsh, J. Bacteriol. 174:5748-5752, 1992). The map position of murZ (69.3 min) differed from that determined for murA (90 min), a gene which had been previously proposed to encode the same activity (P.S. Venkateswaran and H. C. Wu, J. Bacteriol. 110:935-944, 1972). Here we describe the construction of a chromosomal deletion of murZ and a plasmid containing murZ under arabinose control. Growth of cells containing the murZ deletion was dependent on the expression of murZ from the plasmid. We conclude that murZ is an essential gene and encodes the sole UDP-N-acetylglucosamine enolpyruvyl transferase of E. coli. To simplify the nomenclature, we recommend that murA be used to designate the gene at 69.3 min that encodes this activity and that the designation murZ be abandoned.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
