Correlation between Exogenous Compounds and the Horizontal Transfer of Plasmid-Borne Antibiotic Resistance Genes

open access: yesMicroorganisms, 2020
The global spread of antibiotic resistance has posed a serious threat to public healthcare and undermined decades of progress made in the fight against bacterial infections.

The Type IV Secretion System of ICEAfe1: Formation of a Conjugative Pilus in Acidithiobacillus ferrooxidans

open access: yesFrontiers in Microbiology, 2019
The dispersal of mobile genetic elements and their gene cargo relies on type IV secretion systems (T4SS). In this work the ICEAfe1 Tra-type T4SS nanomachine, encoded in the publicly available genome of Acidithiobacillus ferrooxidans ATCC 23270TY, was ...

Direct Conjugation of Resveratrol on Hydrophilic Gold Nanoparticles: Structural and Cytotoxic Studies for Biomedical Applications

open access: yesNanomaterials, 2020
Strongly hydrophilic gold nanoparticles (AuNPs), functionalized with citrate and L-cysteine, were synthetized and used as Resveratrol (RSV) vehicle to improve its bioavailability.

Characterizing conjugative plasmids from an antibiotic-resistant dataset for use as broad-host delivery vectors

open access: yesFrontiers in Microbiology, 2023
Human microbiome engineering is increasingly proposed as a way to modulate health outcomes. However, one of the current limitations to engineering microbial communities in situ is delivery of a genetic payload for introducing or modifying genes.

Peptide-Protein Conjugation and Characterization to Develop Vaccines for Group A Streptococcus

open access: yes, 2021
Peptide conjugates have been widely used for developing vaccines that prevent common bacterial infections for which peptides alone are either ineffective or provide only short-term protection. Among several carrier proteins, diphtheria toxoid and CRM197 (

Transcriptional regulation mediated through the conjugation and deconjugation of the small ubiquitin-like modifiers SUMO-1, SUMO-2, and SUMO-3 [PDF]

open access: yes, 2012
SUMO-1/2/3 are members of the ubiquitin-like family of protein modifiers. These proteins are covalently attached to numerous proteins in a directed and controlled manner.

A purple odyssey: synthesis and structure of 3-amino-4-hydroxy-6-oxocyclohexa-2,4-dien-1-iminium chloride monohydrate

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2016
In the cation of the title hydrated molecular salt, C6H7N2O2+·Cl−·H2O, the six-membered ring shows unequal bond lengths consistent with delocalization of electrons over two separate 6π systems with single bonds between them.

Conjugation spaces are cohomologically pure [PDF]

open access: yes, 2021
Conjugation spaces are equipped with an involution such that the fixed points have the same mod 2 cohomology (as a graded vector space, a ring, and even an unstable algebra) but with all degrees divided by 2, generalizing the classical examples of ...

Differential Requirement for the Cell Wall Integrity Sensor Wsc1p in Diploids Versus Haploids

open access: yesJournal of Fungi, 2021
The primary role of the Cell Wall Integrity Pathway (CWI) in Saccharomyces cerevisiae is monitoring the state of the cell wall in response to general life cycle stresses (growth and mating) and imposed stresses (temperature changes and chemicals). Of the

On Functions with a Conjugate [PDF]

open access: yesAnnales de l'Institut Fourier, 2015
Harmonic functions of two variables are exactly those that admit a conjugate, namely a function whose gradient has the same length and is everywhere orthogonal to the gradient of the original function. We show that there are also partial differential equations controlling the functions of three variables that admit a conjugate.
