Copper coordination to soluble oligomers of the English (AβH(6)R) mutant of the amyloid-β peptide is probed. Cu(II) coordination yields a square planar (N/O)4 coordination environment, while reduction yields an O2 inert linear bis-His Cu(I) centre.

Tablighi Jamaat movement has several proselytizing agendas that are not explicitly stated, but can be seen from the phenomenon of Jama'ah ritual practice which in some aspects carries values tarekat and Sufism. Seeing this phenomenon, research was conducted with aim analyzing Sufi Da'wah Jama'at. This is a qualitative type participatory observation data sources, interviews enriched library data...

In this article, an attempt has been made to make a nuanced study of the images portrayed shaikh by Hamid Qalandar and his protagonist, Shaikh Nasiruddin, in malfuzat entitled Khairul Majalis. It highlights that willingly chose path faqr (poverty), faqa (deprivation/hunger) wanted renounce duniya wa khalq (world people), which resulted antipathy towards shughl (government service) state all its...

Bamboo mosaic virus (BaMV), a member of the potexvirus group, infects primarily members of the Bambusoideae. The open reading frame 1 (ORF1) of BaMV encodes a 155-kDa polypeptide that was postulated to be involved in the replication and the formation of cap structure at the 5' end of the viral genome. To characterize the activities associated with the 155-kDa viral protein, it was expressed in ...

In vitro selection targeting an anti-polyhistidine monoclonal antibody was performed using mRNA display with a random, unconstrained 27-mer peptide library. After six rounds of selection, epitope-like peptides were identified that contain two to five consecutive, internal histidines and are biased for arginine residues, without any other identifiable consensus. The epitope was further refined b...

A hexahistidine-tagged C-terminal nucleotide-binding domain (H6-NBD2) from mouse P-glycoprotein was designed, overexpressed, and purified as a highly soluble recombinant protein. Intrinsic fluorescence of its single tryptophan residue allowed monitoring of high-affinity binding of 2'(3')-N-methylanthraniloyl-ATP (MANT-ATP), a fluorescent ATP derivative that induces a marked quenching correlated...

Recombinant subunit vaccines consisting of the F1 and V antigens of Yersinia pestis have shown remarkable promise for protection of animals and humans against bubonic and pneumonic plague. Previously we demonstrated that intranasal administration of a recombinant protein consisting of the ricin B chain (RTB) fused with an antigen purified from transgenic Nicotiana tabacum (tobacco) hairy root c...
