Few novel cobalt(II) and copper(II) complexes [M(fmp)3]Cl2, [M(fmp)(bpy)2]Cl2,[M(fmp)(phen)2]Cl2 and [M(fmp)(phen)(bpy)]Cl2 (fmp = 3-furan-2-ylmethylene-pentane-2,4-dione, phen = 1,10-phenanthroline, bpy = 2,2'-bipyridine) have been synthesized andcharacterized by elemental analyses, molar conductance, magnetic susceptibility measurements,IR, electronic, EPR, mass spectra and cyclic voltammetri...

ABSTRACT. Metal complexes play an important role in agriculture, pharmacology, medicine, and industrial chemistry. Schiff base metal compounds are the fusion products of propene aldehydes, require a surrounded by ion or cluster molecules to form. Co(II), Ni(II), Cu(II), Zn(II) have also been created. Elemental analysis is used analyses structure related produced ligand. According deoxyribose nu...

Many viruses use a powerful terminase motor to pump their genome inside an empty procapsid shell during virus maturation. The large terminase (TerL) protein contains both enzymatic activities necessary for packaging in such viruses: the adenosine triphosphatase (ATPase) that powers DNA translocation and an endonuclease that cleaves the concatemeric genome at both initiation and completion of ge...

Objective: Berberis vulgaris contains antioxidants that can inhibit DNA cleavage. The purpose of this study was to evaluate the antioxidant and protective activity of B. vulgaris on DNA cleavage. <span style="font-size: medium;"...

DNA topoisomerase II modulates DNA topology by relieving supercoil stress and by unknotting or decatenating entangled DNA. During its reaction cycle, the enzyme creates a transient double-strand break in one DNA segment, the G-DNA. This break serves as a gate through which another DNA segment is transported. Defined topoisomerase II cleavage sites in genomic and plasmid DNA have been previously...

in depth interaction studies between calf thymus deoxyribonucleic acid (ct-dna) and a series of four structurally relative palladium(ii) complexes [pd(en)(hb)](no3)2 (a-d), where en is ethylenediamine and heterocyclic base (hb) is 2,2&apos;-bipyridine (bpy, a); 1,10-phenanthroline (phen, b); dipyridoquinoxaline (dpq, c) and dipyridophenazine (dppz, d) (figure 1), were performed. these studies h...

The BcgI restriction-modification system consists of two subunits, A and B. It is a bifunctional protein complex which can cleave or methylate DNA. The regulation of these competing activities is determined by the DNA substrates and cofactors. BcgI is an active endonuclease and a poor methyltransferase on unmodified DNA substrates. In contrast, BcgI is an active methyltransferase and an inactiv...

Isotherms of the binding of the anthracycIine antibiotic, adriamycin (adriblastin), to DNA histone complexes was studied by means of spectroscopic analysis. The results indicated that: (a) binding of adriamycin to histones reduced the interaction of histones with DNA, (b) binding of the drug to DNA did not change the binding affinity of histone to DNA and, (c) in the explored binding range...
