THE CRYSTAL STRUCTURE OF URACIL-DNA N-GLYCOSYLASE (UNG) FROM DEINOCOCCUS RADIODURANS.
Overview
Uracil-DNA glycosylases are DNA-repair enzymes that catalyse the removal, of promutagenic uracil from single- and double-stranded DNA, thereby, initiating the base-excision repair (BER) pathway. Uracil in DNA can occur, by mis-incorporation of dUMP in place of dTMP during DNA synthesis or by, deamination of cytosine, resulting in U-A or U-G mispairs. The, radiation-resistant bacterium Deinococcus radiodurans has an elevated, number of uracil-DNA glycosylases compared with most other organisms. The, crystal structure of dr0689 (uracil-DNA N-glycosylase), which has been, shown to be the major contributor to the removal of mis-incorporated, uracil bases in crude cell extracts of D. radiodurans, is reported.
