Covalent and non-covalent binding of metal complexes to RNA

Immobilization of Subtilisin Carlsberg on Modified Silica Gel by Cross-linking and Covalent Binding Methods

Proteases are important enzymes that their role in various industries is undeniable. However, keeping enzymes stable during its activity in harsh conditions is so important. In this study, protease enzyme was immobilized on the porous silica particles and its stability in different temperatures and pHs was evaluated. First silica particles were aminated by 3-aminopropyltriethoxysilane then the ...

Non-covalent interactions in coinage metal complexes of 1,2,4-triazole-based N-heterocyclic carbenes.

Seven coinage metal(I) complexes bearing two different triazole-based N-heterocyclic carbene (NHC) ligands, [1-tert-butyl-4-{2-[(N,N-dimethylamino)methyl]phenyl}-3-phenyl-1H-1,2,4-triazol-4-ium-5-ide and 1-tert-butyl-4-(4-methylphenyl)-3-phenyl-1H-1,2,4-triazol-4-ium-5-ide], were synthesized and fully characterized in solution by NMR spectroscopy as well as in the solid state by X-ray diffracti...

Protein Immobilization in Metal-Organic Frameworks by Covalent Binding

Metal-organic Frameworks (MOFs), possessing a well-defined system of pores, demonstrate extensive potential serving as a platform in biological catalysis. Successful immobilization of enzymes in a MOF system retains the enzymatic activity, renders the active site more accessible to the substrate, and promises recyclability for 10 reuse and solvent adaptability in a broad range of working condit...
