Disease relevance of umuD

  • Remarkably, the umuC122::Tn5 allele of umuC, dinB, and certain forms of umuD gene products endow E. coli with the ability to withstand HU treatment (HUR) [1].
  • The umuD and umuC genes were placed under the control of a regulated phage lambda PL promoter and a synthetic ribosome-binding site, and the distance to the UmuD start was adjusted to maximize gene expression [2].
  • The left arm contains a long cluster of structural genes that are closely related to those of the lambda-like phages, but also includes homologs of umuD', which encodes a DNA polymerase accessory protein, and the plasmid partition genes, sopA and sopB [3].
  • The DNA from none of the vibrio species examined including marine vibrios hybridized to E. coli umuC and umuD gene sequences [4].

High impact information on umuD

  • Posttranslational modification of the umuD-encoded subunit of Escherichia coli DNA polymerase V regulates its interactions with the beta processivity clamp [5].
  • To initiate a biochemical characterization of the role of these proteins, we have developed a plasmid system that gives efficient expression of the umuD and umuC genes [2].
  • Furthermore, the search identified an SOS gene within the genome of P1 which encodes a protein that is homologous to UmuD', the RecA-promoted cleavage product of the umuD gene [6].
  • The umuD open reading frame is intact, but it is 1.5 times the size of other umuD genes and has an extra 5' region that lacks homology to known umuD genes [7].
  • The umuD mutation did not affect the growth rate or survival after UV-induced DNA damage [7].

Biological context of umuD


Associations of umuD with chemical compounds


Other interactions of umuD

  • From these and the previous results of genetic and biochemical studies on the cloned genes, we conclude that the former is the umuD and the latter is the umuC gene [14].
