How gut cells distinguish between beneficial symbionts and deleterious pathobionts is a central question. In this issue of Cell Host & Microbe, Kim et al. (2020) demonstrate that the nucleoside catabolism pathway controlling bacterial uracil and ribose production is an essential trigger of the commensal to pathogen transition.

Wobble uridines (U34) are generally modified in all species. U34 modifications can be essential in metazoans but are not required for viability in fungi. In this review, we provide an overview on the types of modifications and how they affect the physico-chemical properties of wobble uridines. We describe the molecular machinery required to introduce these modifications into tRNA posttranscriptionally and discuss how posttranslational regulation may affect the activity of the modifying enzymes. We highlight the activity of anticodon specific RNases that target U34 containing tRNA. Finally, we discuss how defects in wobble uridine modifications lead to phenotypes in different species. Importantly, this review will mainly focus on the cytoplasmic tRNAs of eukaryotes. A recent review has extensively covered their bacterial and mitochondrial counterparts. 1.

The metabolic pathway related to uridine production was modified in Bacillus subtilis in order to increase the production of uridine.
Decreasing the relative transcriptional level of pur operon in Bacillus subtilis TD300 to 80%, and the production of the derived strain TD312 was increased to 11.81 g uridine/l and the yield was increased to 270 mg uridine/g glucose. The expression of pucR gene in situ by PccpA resulting in a 194.01-fold increase in the relative transcriptional level of pucR gene and 349.71-fold increase in the relative transcriptional level of ure operon, respectively. Furthermore, the production of TD314 reached 13.06 g uridine/l, while the yield reached 250 mg uridine/g glucose.
This is the first report that more than 13 g uridine/l with a yield of 250 mg uridine/g glucose is produced in shake flask fermentation of genetically engineered Bacillus subtilis.

Uridin is a glycosylated pyrimidine-analog containing uracil attached to a ribose ring (or more specifically, aribofuranose) via a β-N1-glycosidic bond.
