Mechanisms of base selection by the E.coli mispaired uracil glycosylase [PDF]
, 2008 The repair of the multitude of single-base lesions formed daily in the cells of all living organisms is accomplished primarily by the base-excision repair (BER) pathway that initiates repair through a series of lesion-selective glycosylases.

Pyrimidine biosynthesis in Pseudomonas veronii and its regulation by pyrimidines
Microbiological Research, 2012 Pyrimidine biosynthesis in the nutritionally versatile bacterium Pseudomonas veronii ATCC 700474 appeared to be controlled by pyrimidines. When wild type cells were grown on glucose in the presence of uracil, four enzyme activities were depressed while all five enzyme activities increased in succinate-grown cells supplemented with uracil.
