Chimeric Restriction Enzymes: What Is Next? [PDF]
Biological Chemistry, 1999 Chimeric restriction enzymes are a novel class of engineered nucleases in which the non-specific DNA cleavage domain of Fokl (a type IIS restriction endonuclease) is fused to other DNA-binding motifs. The latter include the three common eukaryotic DNA-binding motifs, namely the helix-turn-helix motif, the zinc finger motif and the basic helix-loop ...

Isothermal in vitro amplification of DNA by a restriction enzyme/DNA polymerase system.
Proceedings of the National Academy of Sciences of the United States of America, 1992 An isothermal in vitro DNA amplification method was developed based upon the following sequence of reaction events. Restriction enzyme cleavage and subsequent heat denaturation of a DNA sample generates two single-stranded target DNA fragments (T1 and T2)

Autophagy in cancer and protein conformational disorders
FEBS Letters, EarlyView.Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Genotyping and antimicrobial resistance patterns of Klebsiella pneumoniae clinical isolates in Suez Canal University Hospitals [PDF]
Microbes and Infectious DiseasesBackground: Health crisis of multi-drug resistant Klebsiella pneumoniae (K. pneumoniae) seems overwhelming. Genotyping for such an important pathogen is a demand to control aggressive Klebsiella infections. Therefore, this study was conducted to identify

FEBS Letters, EarlyView.The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

Activity on non-methylated DNA limits the use of endonuclease MspJI for epigenetic analyses
All Results Journals: Biol, 2018 Cytosine methylation of DNA in mammals has been associated with both physiological and pathological changes in gene-expression. DNA treatment with methylation sensitive and/or dependent restriction enzymes, followed by PCR amplification is a widely used ...

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

FEBS Letters, EarlyView.The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).

FEBS Letters, EarlyView.UDP‐glucuronic acid 4‐epimerase (UGAepi) catalyzes NAD+‐dependent interconversion of UDP‐glucuronic acid (UDP‐GlcA) and UDP‐galacturonic acid (UDP‐GalA) via C4‐oxidation, 4‐keto‐intermediate rotation, and C4‐reduction. Here, Borg et al. examined the role of the substrate's carboxylate group in the enzymic mechanism by analyzing NADH‐dependent reduction
