The emotional sequelae of hysterectomy have long been suggested as a concern of the gynecologist. A review of the literature reveals that there are surely concrete changes in the functioning, attitudes, and behavior of patients who undergo this procedure. Since the gynecologist acts as the "uterus remover," it is our specialty that should be dealing with(More)
We have measured the frequency of the carbon-hydrogen stretching mode of the pro-R and pro-S C4-H bonds of NADH in solution and when bound to pig heart lactate (LDH) or mitochondrial malate (mMDH) dehydrogenases. This is achieved by specifically deuterating the C4 pro-R or pro-S hydrogens of NADH and determining the frequencies of the resulting C4-D(More)
Nicotinamide deamidase (YNDase) has been purified from yeast through the use of a six-step procedure that includes molecular-sieve high performance liquid chromatography. The final preparation was homogeneous by the criteria of sodium dodecyl sulfate-gel electrophoresis, and the enzyme specific activity was determined to be 175 mumol of nicotinate formed(More)
We have measured the Raman spectra of oxidized nicotinamide adenine dinucleotide, NAD+, and its reduced form, NADH, as well as a series of fragments and analogues of NAD+ and NADH. In addition, we have studied the effects of pH as well as deuteration of the exchangeable protons on the Raman spectra of these molecules. In comparing the positions and(More)
We have observed previously that the reactions catalyzed by hypoxanthine/guanine phosphoribosyltransferase (HGPRTase) are activated by Mg(II), Mn(II), and Co(II), and we have defined the mechanism by which these activations proceed [Biochemistry 22, 3419-3424 (1983)]. A more extensive survey of the kinds of metal ions that will activate the HGPRTase(More)
A unique conformation of deoxynucleoside triphosphate substrates bound to Escherichia coli DNA polymerase I has been determined by nuclear magnetic resonance techniques. The effects of Mn(II) bound at the active site of the enzyme on the longitudinal (T1p-1) and transverse (T2p-1) relaxation rates of the alpha, beta, and gamma phosphorus atoms and 5 protons(More)
The binding of the coenzymes NAD+ and NADH to lactate dehydrogenase causes significant changes in the Raman spectra of both of these molecules relative to spectra obtained in the absence of enzyme. The molecular motions of the bound adenine moiety of both NAD+ and NADH as well as adenine containing analogues of these coenzymes produce Raman bands that are(More)
