Journal ArticleDOI
Structure, function and regulation of the DNA-binding protein Dps and its role in acid and oxidative stress resistance in Escherichia coli: a review.
L.N. Calhoun,Y.M. Kwon +1 more
TL;DR: It is proposed that Dps itself plays a role in gene regulation during starvation, ultimately making the cell more resistant to cytotoxic assaults by controlling the expression of genes necessary for (or deleterious to) stress resistance.
Journal ArticleDOI
Speciation of Campylobacter coli, C. jejuni, C. helveticus, C. lari, C. sputorum, and C. upsaliensis by Matrix-Assisted Laser Desorption Ionization--Time of Flight Mass Spectrometry
Robert E. Mandrell,Leslie A. Harden,Anna H. Bates,William G. Miller,William F. Haddon,Clifton K. Fagerquist +5 more
TL;DR: MALDI-TOF MS analysis of 75 additional Campylobacter strains isolated from humans, poultry, swine, dogs, and cats revealed associations of SIBI type with source, strains previously speciated incorrectly, and “strains” composed of more than one species.
Journal ArticleDOI
Profiling the humoral immune response in colon cancer patients: diagnostic antigens from Streptococcus bovis.
Harold Tjalsma,Marie Schöller-Guinard,Edwin Lasonder,Theo J.M. Ruers,Hans L. Willems,Dorine W. Swinkels +5 more
TL;DR: These findings corroborate the hypothesis that colonic lesions provide a specific niche for S. bovis, resulting in tumor‐associated “silent” infections, and make profiling of the humoral immune response against “ silent’ S.bovis infections a promising diagnostic tool for the early detection of human colon cancer, which is crucial for the effective treatment of this disease.
Journal ArticleDOI
Lysine acetylation of the Mycobacterium tuberculosis HU protein modulates its DNA binding and genome organization
TL;DR: It is demonstrated that the DNA binding property of MtHU is regulated by posttranslational modifications akin to eukaryotic histones, and first insights into the modulation of the nucleoid structure by lysine acetylation in bacteria are provided.
Journal ArticleDOI
Modulation of HU–DNA interactions by salt concentration and applied force
TL;DR: It is observed that the dissociation kinetics depend on force applied to the DNA: increased applied force in the sub-piconewton range accelerates dissociation, suggesting a mechanism for DNA tension to regulate chromosome structure and gene expression.

Journal ArticleDOI
A novel nucleoid-associated protein of Mycobacterium tuberculosis is a sequence homolog of GroEL
TL;DR: Findings reveal that M. tuberculosis GroEL1 has evolved to be associated with nucleoids and can effectively function as a DNA-protecting agent against DNase I or hydroxyl-radicals.
Journal ArticleDOI
HupB, a Nucleoid-Associated Protein of Mycobacterium tuberculosis, Is Modified by Serine/Threonine Protein Kinases In Vivo
Meetu Gupta,Andaleeb Sajid,Kirti Sharma,Soumitra Ghosh,Gunjan Arora,Ramandeep Singh,Valakunja Nagaraja,Vibha Tandon,Yogendra Singh +8 more
TL;DR: HupB, a DNA-binding protein, with an ability to modulate chromatin structure is proposed to work in a growth-phase-dependent manner through its phosphorylation carried out by the mycobacterial STPKs.
Journal ArticleDOI
Concentration-dependent organization of DNA by the dinoflagellate histone-like protein HCc3
Yuk-Hang Chan,Joseph T.Y. Wong +1 more
TL;DR: A biophysical role for HCc3 in maintaining extended DNA loops at the periphery of liquid crystalline chromosomes in dinoflagellates is consistent with a nucleosome-based organization of chromosomes in the eukaryotes.
Journal ArticleDOI
HU binds and folds single-stranded DNA
TL;DR: HU binds specifically DNA containing mismatched region longer than 3 bp as well as DNA bulges to single-stranded DNA in a binding mode that is reminiscent but different from earlier reported specific HU interactions with double-helical DNA lesions.
Journal ArticleDOI
Lon protease of the α-proteobacterium Agrobacterium tumefaciens is required for normal growth, cellular morphology and full virulence
TL;DR: The lon mutant of the alpha-proteobacterium Agrobacterium tumefaciens C58 is characterized, suggesting that Lon may be required for the proper expression, assembly or function of the VirB/D4-mediated T-DNA transfer system.
