Regulation of bistability in the std fimbrial operon of Salmonella enterica by DNA adenine methylation and transcription factors HdfR, StdE and StdF
(Oxford Academic, 2019-09-05)
Bistable expression of the Salmonella enterica std operon is controlled by an AND logic gate involving three transcriptional activators: the LysR-type factor HdfR and the StdE and StdF regulators encoded by the std operon ...

Contribution of DNA adenine methylation to gene expression heterogeneity in Salmonella enterica
(Oxford University Press, 2020)
Expression of Salmonella enterica loci harboring undermethylated GATC sites at promoters or regulatory regions was monitored by single cell analysis. Cell-to-cell differences in expression were detected in ten such loci ...

Ribosomal protein L14 contributes to the early assembly of 60S ribosomal subunits in Saccharomyces cerevisiae
(Oxford University Press, 2018)
The contribution of most ribosomal proteins to ribo- some synthesis has been quite well analysed in Sac- charomyces cerevisiae . However, few yeast riboso- mal proteins still await characterization. Herein, we show ...

Human mitochondrial degradosome prevents harmful mitochondrial R loops and mitochondrial genome instability
(2018)
R loops are nucleic acid structures comprising an DNA-RNA hybrid and a displaced single-stranded DNA. These structures may occur transiently during transcription, playing essential biological functions. However, persistent ...

A novel lncRNA as a positive regulator of carotenoid biosynthesis in Fusarium
(Nature Research, 2020)
The fungi Fusarium oxysporum and Fusarium fujikuroi produce carotenoids, lipophilic terpenoid pigments of biotechnological interest, with xanthophyll neurosporaxanthin as the main end product. Their carotenoid biosynthesis ...
