Controlled Transcription of Regulator Gene carS by Tet-on or by a Strong Promoter Confirms Its Role as a Repressor of Carotenoid Biosynthesis in Fusarium fujikuroi
(MDPI, 2020-12)
Carotenoid biosynthesis is a frequent trait in fungi. In the ascomycete Fusarium fujikuroi, the synthesis of the carboxylic xanthophyll neurosporaxanthin (NX) is stimulated by light. However, the mutants of the carS gene, ...

Surface modulation of single-walled carbon nanotubes for selective bacterial cell agglutination
(Dove Medical Press, 2019)
Background: Bacterial resistance to antibiotics is one of the biggest challenges facing medicine today. Anti-adhesive therapy, using inhibitors of bacterial adhesion to epithelial cells, one of the first stages of ...

Functional Characterization of Lysophosphatidylcholine: Acyl-CoA Acyltransferase Genes From Sunflower (Helianthus annuus L.)
(MDPI, 2020)
Lysophosphatidylcholine acyltransferase (LPCAT, EC 2.3.1.23) is an evolutionarily conserved key enzyme in the Lands cycle that catalyzes acylation of lysophosphatidylcholine (LPC) to produce phosphatidylcholine (PC), the ...

Pol5 is an essential ribosome biogenesis factor required for 60S ribosomal subunit maturation in Saccharomyces cerevisiae
(Cold Spring Harbor Laboratory Press, 2019)
In Saccharomyces cerevisiae, more than 250 trans-acting factors are involved in the maturation of 40S and 60S ribosomal subunits. The expression of most of these factors is transcriptionally coregulated to ensure correct ...

Physical proximity of chromatin to nuclear pores prevents harmful R loop accumulation contributing to maintain genome stability
(National Academy of Sciences, 2017)
During transcription, the mRNA may hybridize with DNA, forming an R loop, which can be physiological or pathological, constituting in this case a source of genomic instability. To understand the mechanism by which eukaryotic ...

One step back before moving forward: regulation of transcription elongation by arrest and backtracking
(Wiley-Blackwell, 2012)
RNA polymerase II backtracking is a well-known phenomenon, but its involvement in gene regulation is yet to be addressed. Structural studies into the backtracked complex, new reactivation mechanisms and genome-wide approaches ...

Adaptation of Salmonella enterica to bile: essential role of AcrAB-mediated efflux
(Society for Applied Microbiology, 2018)
Adaptation to bile is the ability to endure the lethal effects of bile salts after growth on sublethal concentrations. Surveys of adaptation to bile in Salmonella enterica ser. Tyhimurium reveal that active efflux is ...

Proteomic insight into the effects of the Salmonella ubiquitin ligase SlrP on host cells
(Elsevier, 2016)
The virulence of the human and animal pathogen Salmonella enterica serovar Typhimurium is dependent on two type III secretion systems. These systems translocate proteins called effectors into eukaryotic host cells. SlrP ...

New Insights Into Sunflower (Helianthus annuus L.) FatA and FatB Thioesterases, Their Regulation, Structure and Distribution
(Frontiers Media, 2018)
Sunflower seeds (Helianthus annuus L.) accumulate large quantities of triacylglycerols (TAG) between 12 and 28 days after flowering (DAF). This is the period of maximal acyl-acyl carrier protein (acyl-ACP) thioesterase ...
