Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

open access: yesFEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Bioaffinity chromatography /

open access: yes, 1993
Bioaffinity chromatography is now the preferred choice for the purification, determination or removal of many biologically active substances. The book includes information on biologically active substances with their affinants, solid supports and methods

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Purification of a streptococcal deoxyribonuclease by affinity chromatography based on a DNA-cellulose matrix

open access: yes, 1997
An affinity chromatography method, using double stranded DNA, is described for the isolation of a deoxyribonuclease from the medicament Varidase, a wound cleansing preparation produced from the extracellular products of a species of Streptococcus.

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

open access: yesFEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Affinity chromatography of milk sIgAs on different affinity sorbent.

open access: yes, 2013
Affinity chromatography of milk sIgA-1 preparation on anti-κ-L-Sepharose under the conditions of over-saturation of the affinity capacity of the sorbent (A) and re-chromatography of the preparation eluted by acidic buffer (peak 2) on anti-λ-L-Sepharose ...

Reaction of Native and Denatured Brucella abortus (S19) Proteins with Antibody Using Affinity Chromatography and Immunoblotting

open access: yesپزشکی بالینی ابن سینا, 2005
Western blotting or immunoblotting commonly use for study of reaction between antigens and antibodies. Denaturation of many proteins in immunoblotting can affect greatly the reactivity of antibodies and outcome of the procedure.

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.
