A degenerate PCR-based strategy as a means of identifying homologues of aminoglycoside and ß-lactam resistance genes in the gut microbiota [PDF]

open access: yes, 2014
peer-reviewedBackground: The potential for the human gut microbiota to serve as a reservoir for antibiotic resistance genes has been the subject of recent discussion. However, this has yet to be investigated using a rapid PCR-based approach.

N-terminal acetylation shields proteins from degradation and promotes age-dependent motility and longevity

open access: yesNature Communications, 2023
Most eukaryotic proteins are N-terminally acetylated, but the functional impact on a global scale has remained obscure. Using genome-wide CRISPR knockout screens in human cells, we reveal a strong genetic dependency between a major N-terminal ...

Determination of the Biochemical Activity of N-Acetyltransferase Enzyme, NAT2 Gene Production in Children with Environmental Pathology Following Received Treatment

open access: yesZdorovʹe Rebenka, 2016
The study of the biochemical activity of the enzyme N-acetyltransferase, NAT2 gene production in children from ecologically unfavorable regions (EUR) is extremely important to identify predisposition to environmental pathology, including thyroid, renal ...

Charge environments around phosphorylation sites in proteins [PDF]

open access: yes, 2008
Background: Phosphorylation is a central feature in many biological processes. Structural analyses have identified the importance of charge-charge interactions, for example mediating phosphorylation-driven allosteric change and protein binding to ...

Phage ϕC2 mediates transduction of Tn6215, encoding erythromycin resistance, between Clostridium difficile strains [PDF]

open access: yes, 2013
UNLABELLED: In this work, we show that Clostridium difficile phage ϕC2 transduces erm(B), which confers erythromycin resistance, from a donor to a recipient strain at a frequency of 10(-6) per PFU.

A Continuous Assay Set to Screen and Characterize Novel Protein N-Acetyltransferases Unveils Rice General Control Non-repressible 5-Related N-Acetyltransferase2 Activity

open access: yesFrontiers in Plant Science, 2022
Protein N-acetyltransferases (NATs) belong to the general control non-repressible 5 (Gcn5)-related N-acetyltransferases (GNATs) superfamily. GNATs catalyze the transfer of acetyl from acetyl-CoA to the reactive amine moiety of a wide range of acceptors ...

Genetic disruption of the core circadian clock impairs hippocampus-dependent memory [PDF]

open access: yes, 2014
Perturbing the circadian system by electrolytically lesioning the suprachiasmatic nucleus (SCN) or varying the environmental light:dark schedule impairs memory, suggesting that memory depends on the circadian system.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Molecular basis of antibiotic self-resistance in a bee larvae pathogen

open access: yesNature Communications, 2022
The authors show that the N-acetyltransferase PamZ acts as a self-resistance factor disabling the antibacterial paenilamicin that is produced by the honey bee larvae pathogen Paenibacillus larvae.

BCG vaccination and leprosy protection: review of current evidence and status of BCG in leprosy control.

open access: yes, 2010
The bacillus Calmette-Guérin (BCG) vaccine, initially developed to provide protection against TB, also protects against leprosy; and the magnitude of this effect varies. Previous meta-analyses did not provide a summary estimate of the efficacy due to the
