Restriction-modification systems of M. gallisepticum S6.

, 2022
Arrows represent the ORFs; grey, blue, green, and orange colors indicate genes hsdC (controller protein), hsdM (methyltransferase), hsdS (specificity subunit), and hsdR (restriction subunit), respectively. Ori–origin of replication.

Domain movement within a gene: a novel evolutionary mechanism for protein diversification. [PDF]

PLoS ONE, 2011
A protein function is carried out by a specific domain localized at a specific position. In the present study, we report that, within a gene, a specific amino acid sequence can move between a certain position and another position.

DNA methylation assessed by SMRT sequencing is linked to mutations in Neisseria meningitidis isolates [PDF]

, 2015
The Gram-negative bacterium Neisseria meningitidis features extensive genetic variability. To present, proposed virulence genotypes are also detected in isolates from asymptomatic carriers, indicating more complex mechanisms underlying variable ...

Functional comparison of anti-restriction and anti-methylation activities of ArdA, KlcA, and KlcAHS from Klebsiella pneumoniae

Frontiers in Cellular and Infection Microbiology, 2022
Anti-restriction proteins are typically encoded by plasmids, conjugative transposons, or phages to improve their chances of entering a new bacterial host with a type I DNA restriction and modification (RM) system.

Effect of a standardised dietary restriction protocol on multiple laboratory strains of Drosophila melanogaster [PDF]

, 2009
Background: Outcomes of lifespan studies in model organisms are particularly susceptible to variations in technical procedures. This is especially true of dietary restriction, which is implemented in many different ways among laboratories.

Avoidance of recognition sites of restriction-modification systems is a widespread but not universal anti-restriction strategy of prokaryotic viruses

BMC Genomics, 2018
Background Restriction-modification (R-M) systems protect bacteria and archaea from attacks by bacteriophages and archaeal viruses. An R-M system specifically recognizes short sites in foreign DNA and cleaves it, while such sites in the host DNA are ...

Restriction and decay for flat hypersurfaces [PDF]

, 2002
In the first part we consider restriction theorems for hypersurfaces [Gamma] in Rn, with the affine curvature [fòrmula] introduced as a mitigating factor. Sjolin, [19], showed that there is a universal restriction theorem for all convex curves in R2.

REMP software to introduce a screening REstriction site in site-directed Mutagenesis Primer

SoftwareX, 2021
Insertion of silent mutations allowing for restriction site modification aids in the screening of successful mutants during site directed mutagenesis. Introducing a new restriction site requires the analysis of degenerate sequences within mutant primer ...

Historical Aspects of Restriction Endonucleases as Intelligent Scissors for Genetic Engineering

Fermentation, 2023
Restriction endonucleases are a component of restriction–modification systems, where the main biological function is to protect bacterial cells from incoming foreign DNA molecules.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
