Light-dependent functions of the Fusarium fujikuroi CryD DASH cryptochrome in development and secondary metabolism
(American Society for Microbiology, 2013)
DASH (Drosophila, Arabidopsis, Synechocystis, human) cryptochromes (cry-DASHs) constitute a subgroup of the photolyase cryptochrome family with diverse light-sensing roles, found in most taxonomical groups. The genome of ...

Caracterización funcional de dos efectores de los sistemas de secreción tipo III de salmonella y estudio de su impacto en el hospedador
(2015-02-02)
Numerosas bacterias patógenas Gram negativas poseen sistemas de secreción tipo III (SST3) relacionados con la virulencia que les permiten translocar proteínas, denominadas efectores, desde la bacteria hacia la célula ...

Bioavailability and provitamin A activity of neurosporaxanthin in mice
(Nature Publishing Group, 2023-10-20)
Various species of ascomycete fungi synthesize the carboxylic carotenoid neurosporaxanthin. The unique chemical structure of this xanthophyll reveals that: (1) Its carboxylic end and shorter length increase the polarity ...

The ubiquitin E3/E4 ligase, UBE4A, fine-tunes protein ubiquitylation and accumulation at sites of DNA damage facilitating double-strand break repair
(Elsevier, 2018)
Double-strand breaks (DSBs) are critical DNA lesions that robustly activate the elaborate DNA damage response (DDR) network. We identified a critical player in DDR fine-tuning - the E3/E4 ubiquitin ligase, UBE4A. UBE4A’s ...

Copy Number Heterogeneity in the Virulence Plasmid of Salmonella enterica
(Frontiers Media, 2020)
Quantitative PCR analysis shows that the virulence plasmid of Salmonella enterica serovar Typhimurium (pSLT) is a low-copy-number plasmid, with 1–2 copies per chromosome. However, fluorescence microscopy observation of ...

Mechanism of coordinated synthesis of the antagonistic regulatory proteins NifL and NifA of Klebsiella pneumoniae
(American Society for Microbiology, 1996-12)
The nifLA operon of Klebsiella pneumoniae codes for the two antagonistic regulatory proteins which control expression of all other nitrogen fixation genes. NifA is a transcriptional activator, and NifL inhibits NifA. The ...

Regulation of the Salmonella enterica std fimbrial operon by DNA adenine methylation, SeqA, and HdfR
(American Society for Microbiology, 2008)
DNA adenine methylase (dam) mutants of Salmonella enterica serovar Typhimurium grown under laboratory conditions express the std fimbrial operon, which is tightly repressed in the wild type. Here, we show that uncontrolled ...
