The structure of metaphase chromosomes. I. Electrometric titration, magnesium ion binding and circular dichroism.
Isolated mammalian metaphase chromosomes suspended in ion-free or 10d3 YN&l solution undergo an irreversible, pH-dependent structural change, as reflected by electrometric titrations, pH-stat experiments and measurements of circular dichroism spectra. Unmasking of titratable groups with pK’s lower than the isoionic pH of chromosomes in ion-free water, pH 66, accompanies the change in conformati...
متن کاملUse of circular dichroism for assigning stereochemistry of sphingosine and other long-chain bases.
Sphingolipid signal transduction pathways are mediated by a wide variety of enzyme-substrate interactions. The key factor that ensures the fidelity of this pathway is the specificity between each enzyme and substrate. The specificity can be understood in terms of the molecular-level interactions, in which the asymmetric protein binding site accommodates its chiral substrate stereospecifically. ...
متن کاملCircular Dichroism of Light-harvesting Complexes from Purple Photosynthetic Bacteria*
The CD spectra of a range of antenna complexes from several different species of purple photosynthetic bacteria were recorded in the wavelength range of 190 to 930 nm. Analysis of the far UV CD (190 to 250 nm) showed that in each case except for the B800-850 from Chr. vinosum the secondary structure of the light-harvesting complexes contains a large amount of a-helix ( 2 5 0 % ) and very little...
متن کاملMagnetic circular dichroism of porphyrin lanthanide M3+ complexes.
Lanthanide complexes exhibit interesting spectroscopic properties yielding many applications as imaging probes, natural chirality amplifiers, and therapeutic agents. However, many properties are not fully understood yet. Therefore, we applied magnetic circular dichroism (MCD) spectroscopy, which provides enhanced information about the underlying electronic structure to a series of lanthanide co...
