Complexes between DNA and polyamines: a molecular model
Abstract A molecular model has been built to explain complex formation between DNA and spermine or spermidine. This model has been derived on the basis of the results obtained from the X-ray analysisExpand
Interaction between DNA and polycyclic aromatic hydrocarbons
The results obtained in solubilization experiments of benzpyrene and dibenz-anthracene in DNA—water solutions, in conjunction with observed changes in the u.v. absorption and fluorescence spectra ofExpand
A proposal of standard conventions and nomenclature for the description of polypeptide conformation.
Influence of thermal denaturation on the electrophoretic mobility of calf thymus DNA
The results of electrophoresis experiments on aqueous solutions of native and thermally denatured DNA are reported. A significant decrease of the electrophoretic mobility has been observed followingExpand
A physico-chemical study on the polysaccharide ulvan from hot water extraction of the macroalga Ulva.
The spectroscopic properties and ion binding capacity of this charged polysaccharide were studied by circular dichroism and isothermal microcalorimetric titrations in order to gain information on the potential exploitation of this low cost biomass. Expand
The crystal structure of spermine tetrahydrochloride
+ + + + Crystals of spermine tetrahydrochloride, NH3[CH2]3NHE[CHz]4NH2[CHz]3NH3.4C1-, are monoclinic, space group P21/c, with 2 formula units in a cell with dimensions: a = 8.60, b = 7.88, c = 15.26Expand
