Recurrent features of the thinking pattern (or mind-set) of violent militant extremists are delineated, discussed, and related to previous research and theory. We examined extremist groups from a diverse range of continents, cultures, and political and religious orientations. We compared statements by (and, to some degree, statements about) these groups and formulated 16 themes common to the mi...

Abstract: 
 This research is oriented to analyze the use of Youtube as a learning media religious tolerance for virtual communities. The focus on "jeda nulis" youtube channel with content "toleran dalam berdakwah, dakwahkan toleransi." was conducted based reality rise radical Islamic accounts that spread negative in form teachings are easy disbelieve and convert those who have different un...

BACKGROUND A versatile strategy for protein-surface coupling in biochips exploits the affinity for polyhistidine of the nitrilotriacetic acid (NTA) group loaded with Ni(II). Methods based on optical reflectivity measurements such as spectroscopic ellipsometry (SE) allow for label-free, non-invasive monitoring of molecule adsorption/desorption at surfaces. RESULTS This paper describes a SE stu...

Here we describe a generic procedure for the expression and purification of milligram quantities of functional recombinant eukaryotic integral membrane proteins, exemplified by hexahistidine-tagged bovine rhodopsin. These quantities were obtained with the recombinant baculovirus/Sf9 insect cell-based expression system in large-scale bioreactor cultures with the use of a serum-free and protein-f...

The crystal structure of a mutant form of the single-chain fragment (scFv), derived from the monoclonal anti-His tag antibody 3D5, in complex with a hexahistidine peptide has been determined at 2.7 A resolution. The peptide binds to a deep pocket formed at the interface of the variable domains of the light and the heavy chain, mainly through hydrophobic interaction to aromatic residues and hydr...

The cDNA of the human GM2-activator protein was cloned into the expression vector pHX17. The plasmid encodes a fusion protein with a hexahistidine tail and a Factor Xa cleavage site at its N-terminus. The recombinant protein was purified from cell homogenates under denaturing conditions by metal-ion affinity chromatography in a single step and then was refolded. The hexahistidine tail could be ...

We report oriented immobilization of proteins using the standard hexahistidine (His6)-Ni2+:NTA (nitrilotriacetic acid) methodology, which we systematically tuned to give control of surface coverage. Fluorescence microscopy and surface plasmon resonance measurements of self-assembled monolayers (SAMs) of red fluorescent proteins (TagRFP) showed that binding strength increased by 1 order of magni...

The fungal pathogen Colletotrichum lindemuthianum secretes an endo-chitin de-N-acetylase (ClCDA) to modify exposed hyphal chitin during penetration and infection of plants. Although a significant amount of biochemical data is available on fungal chitin de-N-acetylases, no structural data exist. Here we describe the 1.8 A crystal structure of a ClCDA product complex and the analysis of the react...

The development of synthetic, low-molecular-weight ligand receptor systems for the selective control of biomolecular interactions remains a major challenge. Binding of oligohistidine peptides to chelators containing Ni2+-loaded nitrilotriacetic acid (NTA) moieties is one of the most widely used and best-characterised recognition systems. Recognition units containing multiple NTA moieties (multi...

Insolubility of recombinant proteins in Escherichia coli is a major impediment to their production for structural and functional studies. One way to circumvent this problem is to fuse an aggregation-prone protein to a highly soluble partner. E. coli maltose-binding protein (MBP) has emerged as one of the most effective solubilizing agents. In this chapter, we describe how to construct combinato...
