pFAR plasmids: New Eukaryotic Expression Vectors for Gene Therapy, devoid of Antibiotic Resistance Markers [PDF]

, 2008
Efficient production of eukaryotic expression vectors requires the selection of plasmid-containing bacteria. To avoid the risk of dissemination of antibiotic resistance markers, we developed a new system to produce a family of plasmids Free of Antibiotic

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Organization of aerobactin, hemolysin, and antibacterial resistance genes in lactose negative Escherichia coli strains of serotype O4 isolated from children with dhiarrea [PDF]

, 1992
Epidemiologically related, non-lactose-fermenting (NLF) Escherichia coli strains of serotype O4 have been isolated at a high frequency from children with diarrhea in Somalia (M. Nicoletti, F. Superti, C. Conti, A. Calconi, and C. Zagaglia, J.

Bacteriophages limit the existence conditions for conjugative plasmids [PDF]

, 2015
Bacteriophages are a major cause of bacterial mortality and impose strong selection on natural bacterial populations, yet their effects on the dynamics of conjugative plasmids have rarely been tested.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Genomic Insights into Marinovum sedimenti sp. nov., Isolated from Okhotsk Sea Bottom Sediments, Suggest Plasmid-Mediated Strain-Specific Motility

Microorganisms
Two Gram-negative aerobic halophilic bacteria, designated KMM 9989T and KMM 9879, were isolated from a bottom sediment sample of the Okhotsk Sea, Russia. The novel strains grew in 0.5–4% NaCl, at 5–35 °C and pH 5.5–10.0.

Unique features of Plasmids among different Citrobacter species [PDF]

, 2012
The _Citrobacter_ plasmids are supposed to represent the host genetic association within the living bacterial cell. The plasmids impart various beneficial characteristics to the host, helping it to retain suitable characteristics for adaptation as well ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
