Two-dimensional NMR spectroscopy has been used to monitor the pH dependences of proton chemical shifts for turkey ovomucoid third domain (OMTKY3). Sample pH was varied from 7.0 to 1.4 in order to determine the apparent pKa values of all six carboxyl groups in OMTKY3. At 35 degrees C and in the presence of 10 mM KCl, the pKa values for Asp 7, Glu 19, and Asp(More)
Kinetics of the synthesis of adducts between salmon testis DNA and platinum(II) compounds were measured by their effects on DNA synthesis, circular dichroism, and ethidium bromide dependent fluorescence. Transient incorporation of [14C]cyanide into DNA adducts of of cis-diammineaquochloroplatinum(II) and respectively cis-diamminediaquoplatinum(II) compounds(More)
The tumor-inhibiting metal complex trans-imidazolium-bisimidazoletetrachlororuthenate(III) (ICR) reacts with DNA and inhibits template-primer properties for DNA synthesis catalysed by Escherichia coli DNA polymerase I. The reaction with DNA depends on the aging (half-life 6.8 h) of the aqueous solution containing ICR. The kinetics of the reaction with DNA(More)
