Presence and distribution of the endosymbiont Wolbachia among Solenopsis spp. (Hymenoptera: Formicidae) from Brazil and its evolutionary history
(2012-03-01)
Wolbachia are intracellular bacteria that commonly infect arthropods. Its prevalence among ants of the genus Solenopsis is high. In the present study, the presence and distribution of these endosymbionts was examined among ...

Periplasmic proteins of the extremophile Acidithiobacillus ferrooxidans
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2007-10-02)
Acidithiobacillus ferrooxidans is a chemolithoautotrophic
acidophile capable of obtaining energy by oxidizing ferrous
iron or sulfur compounds such as metal sulfides. Some of
the proteins involved in these oxidations ...
Haemophilus influenzae porine ompP2 gene transfer mediated by graphene oxide nanoparticles with effects on transformation process and virulence bacterial capacity
(Biomed Central LtdLondonInglaterra, 2014)
Membrane anchoring stabilizes and favors secretion of New Delhi metallo-β-lactamase
(Nature Publishing Group, 2016-07)
Carbapenems, 'last-resort' β-lactam antibiotics, are inactivated by zinc-dependent metallo-β-lactamases (MBLs). The host innate immune response withholds nutrient metal ions from microbial pathogens by releasing metal-chelating ...
Protein determinants of dissemination and host specificity of metallo-β-lactamases
(Nature Publishing Group, 2019-08)
The worldwide dissemination of metallo-β-lactamases (MBLs), mediating resistance to carbapenem antibiotics, is a major public health problem. The extent of dissemination of MBLs such as VIM-2, SPM-1 and NDM among Gram-negative ...
Effects of the antimicrobial peptide PGLa on live Escherichia coli
(Elsevier Science BvAmsterdamHolanda, 2003)
Transcription of TP0126, Treponema pallidum putative OmpW homolog, is regulated by the length of a homopolymeric guanosine repeat
(American Society for Microbiology, 2015)
An effective mechanism for introduction of phenotypic diversity within a bacterial population exploits changes in the length of repetitive DNA elements located within gene promoters. This phenomenon, known as phase variation, ...
RBPI21 interacts with negative membranes endothermically promoting the formation of rigid multilamellar structures
(2013-08-27)
rBPI21 belongs to the antimicrobial peptide and protein (AMP) family. It has high affinity for lipopolysaccharide (LPS), acting mainly against Gram-negative bacteria. This work intends to elucidate the mechanism of action ...
