Mussel adhesive proteins have been suggested as a basis for environmentally friendly adhesives for use in aqueous conditions and in medicine. However, attempts to produce functional and economical recombinant mussel adhesive proteins (mainly foot protein type 1) in several systems have failed. Here, the cDNA coding for Mytilus galloprovincialis foot protein type 5 (Mgfp-5) was isolated for the ...

Natural proteins are often confined within their local microenvironments, such as three-dimensional confinement in organelles or two-dimensional confinement in lipid rafts on cytoplasmic membrane. Spatial confinement restricts proteins' entropic freedom, forces their lateral interaction, and induces new properties that the same proteins lack at the soluble state. So far, the phenomenon of envir...

The αvβ6 integrin is up-regulated in cancer and wound healing but it is not generally expressed in healthy adult tissue. There is increasing evidence that it has a role in cancer progression and will be a useful target for antibody-directed cancer therapies. We report a novel recombinant diabody antibody fragment that targets specifically αvβ6 and blocks its function. The diabody was engineered...

We previously expressed VbhTA constructs for lysate AMPylation assays from the pRSFDuet-1 backbone, a plasmid with two multiple cloning sites that each enable the expression of constructs from a PT7 promoter. Our constructs encoded either the VbhT toxin alone (with an N-terminal hexahistidine (His6-)tag) to be expressed from the first multiple cloning site or had additionally the VbhA antitoxin...

In the presence of a low pH environment, the channel-forming T domain of diphtheria toxin undergoes a conformational change that allows for both its own insertion into planar lipid bilayers and the translocation of the toxin's catalytic domain across them. Given that the T domain contributes only three transmembrane segments, and the channel is permeable to ions as large as glucosamine(+) and N...

Mussel adhesive proteins, including the 20-plus variants of foot protein type 3 (fp-3), have been suggested as potential environmentally friendly adhesives for use in aqueous conditions and in medicine. Here we report the novel production of a recombinant Mytilus galloprovincialis foot protein type 3 variant A (Mgfp-3A) fused with a hexahistidine affinity ligand in Escherichia coli and its appr...

There is a particular need in protein analysis and purification for specific, functional, and generic methods of protein immobilization on solid supports. Here we describe a double-hexahistidine (His6) tag sequence, comprising two hexahistidines separated by an 11-amino acid spacer, which shows at least 1 order of magnitude stronger binding to Ni-NTA-modified surfaces than a conventional single...

mohammad akram (ghanimat-e-konjahi) was from gujarat, india and lived during the era of alamgir king (eleventh and twelfth centuries). in his poetry, one can find new ideas and delicate senses especially in his neirang-e-eshgh, which is also known as ghanimat. his complete collection of poetry consists of lyrics, elegies and quatrains. in his poetry, ghanimat has followed great masters of poetr...

John Maxwell Fairley was a prolific collector and amassed quite a collection of old dental instruments, obtained mainly from the North East of Scotland. John qualified LDS in 1941 and a year later graduated BDS from St Andrews University. He was a member of the Lindsay Society in 1985 and on the committee from 1988 until 1990. One of his contributions to dental history was a comprehensive accou...
