Effects of the pyrE deletion mutant from Bacillus thuringiensis on gut microbiota and immune response of Spodoptera exigua

Frontiers in Microbiology, 2023
The gut microbiota is essential for the growth and development of insects, and the intestinal immune system plays a critical role in regulating the homeostasis of intestinal microorganisms and their interactions with pathogenic bacteria.

Uracil-Induced Down-Regulation of the Yeast Uracil Permease [PDF]

Journal of Bacteriology, 1999
ABSTRACT In Saccharomyces cerevisiae the FUR4 -encoded uracil permease catalyzes the first step of the pyrimidine salvage pathway. The availability of uracil has a negative regulatory effect upon its own transport.

Architecturally diverse proteins converge on an analogous mechanism to inactivate Uracil-DNA glycosylase [PDF]

, 2013
Uracil-DNA glycosylase (UDG) compromises the replication strategies of diverse viruses from unrelated lineages. Virally encoded proteins therefore exist to limit, inhibit or target UDG activity for proteolysis.
