ung uracil-DNA glycosylase [Escherichia coli str. K-12 substr. MG1655] - Gene

Summary

Go to the top of the page Help

Gene symbol: ung
Gene description: uracil-DNA glycosylase
Primary source: ASAP:ABE-0008495
Locus tag: b2580
See related: ECOCYC:EG11058
Gene type: protein coding
RefSeq status: PROVISIONAL
Organism: Escherichia coli str. K-12 substr. MG1655 (strain: K-12, substrain: MG1655)
Lineage: Bacteria; Pseudomonadota; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
Also known as: ECK2578
Summary: UDG and Ndk form a complex (Goswami, 2006). [More information is available at EcoGene: EG11058]. Uracil can be generated in DNA as a result of misincorporation by DNA polymerase, spontaneous deamination of cytosine, and deamination of cytosine induced by bisulfite or nitrous acid. [More information is available at EcoCyc: EG11058].
