Importance of uracil DNA glycosylase in Pseudomonas aeruginosa and Mycobacterium smegmatis, G+C-rich bacteria, in mutation prevention, tolerance to acidified nitrite, and endurance in mouse macrophages.

Abstract excerpt

Uracil DNA glycosylase (Ung (or UDG)) initiates the excision repair of an unusual base, uracil, in DNA. Ung is a highly conserved protein found in all organisms. Paradoxically, loss of this evolutionarily conserved enzyme has not been seen to result in severe growth phenotypes in the cellular lif...
