Characterization of Inner and Outer Membrane Proteins from Francisella tularensis Strains LVS and Schu S4 and Identification of Potential Subunit Vaccine Candidates

mBio, 2017
Francisella tularensis is the causative agent of tularemia and a potential bioterrorism agent. In the present study, we isolated, identified, and quantified the proteins present in the membranes of the virulent type A strain, Schu S4, and the attenuated ...

Reaction‐controlled microgel‐lipase co‐stabilized compartmentalized emulsion for recyclable biodiesel production

Aggregate, 2023
Pickering emulsions have been widely used for biphasic catalysis in the past decade. However, it remains a great challenge to achieve simple product collection and enzyme recovery.

Two homologous EF-G proteins from Pseudomonas aeruginosa exhibit distinct functions. [PDF]

PLoS ONE, 2013
Genes encoding two proteins corresponding to elongation factor G (EF-G) were cloned from Pseudomonas aeruginosa. The proteins encoded by these genes are both members of the EFG I subfamily. The gene encoding one of the forms of EF-G is located in the str

The poly(A)‐binding protein facilitates in vitro translation of poly(A)‐rich mRNA [PDF]

European Journal of Biochemistry, 1988
To investigate the role of the 73‐kDa poly(A)‐binding protein in protein synthesis, the effect of the addition of homo‐polyribonucleotides on the translation of polyadenylated and non‐adenylated mRNA was studied in the rabbit reticulocyte lysate. Poly(A) was found to be the most effective polynucleotide in inhibiting duck‐globin mRNA translation ...

Poly(A) RNAs including coding proteins RNAs occur in plant Cajal bodies.

PLoS ONE, 2014
The localisation of poly(A) RNA in plant cells containing either reticular (Allium cepa) or chromocentric (Lupinus luteus, Arabidopsis thaliana) nuclei was studied through in situ hybridisation. In both types of nuclei, the amount of poly(A) RNA was much

Regulation of Poly(A)-binding Protein through PABP-interacting Proteins

Cold Spring Harbor Symposia on Quantitative Biology, 2006
Translation initiation requires the participation of eukaryotic translation initiation factors (eIFs). The poly(A)-binding protein (PABP) is thought to stimulate translation by promoting mRNA circularization through simultaneous interactions with eIF4G and the 3' poly(A) tail.

ADP-ribose polymer - a novel and general biomarker of human cancers of head & neck, breast, and cervix

Molecular Cancer, 2010
Background Poly-ADP-ribosylation, a reversible post-translational modification of primarily chromosomal proteins, is involved in various cellular and molecular processes including carcinogenesis.

mRNA stabilization by poly(A) binding protein is independent of poly(A) and requires translation [PDF]

Genes & Development, 1998
Translation and mRNA stability are enhanced by the presence of a poly(A) tail. In vivo, the tail interacts with a conserved polypeptide, poly(A) binding protein (Pab1p). To examine Pab1p function in vivo, we have tethered Pab1p to the 3′ UTR of reporter mRNAs by fusing it to MS2 coat protein and placing MS2 binding sites in the 3′ UTR of the reporter ...

Surface Exposure of PEG and Amines on Biodegradable Nanoparticles as a Strategy to Tune Their Interaction with Protein-Rich Biological Media

Nanomaterials, 2019
Nanoparticles (NPs) based on amphiphilic block copolymers of polyethylene glycol (PEG) and biodegradable polyesters are of particular current interest in drug nanodelivery due to their easily manipulated properties.
