A model is proposed for the active center of cytochrome c oxidase (ferrocytochrome c:oxygen oxidoreductase, EC 1.9.3.1) in which cytochrome a is a low-spin ferrihemoprotein and cytochrome a3 is a high-spin ferrihemoprotein antiferromagnetically coupled to one of the two Cu2+ ions present in the enzyme. It is further proposed that reduction is accompanied ...

Streptomyces coelicolor A3(2) produces an antibiotic, actinorhodin, which belongs to the aromatic polyketides and which can function as an acid/base indicator. Its production results in the death of microorganisms in the vicinity of S. coelicolor A3(2), and this phenomenon can be used in concert with biopesticides. ...

Cytochrome c oxidase (CcO), found in the inner mitochondrial membranes or in many bacteria, catalyzes the four-electron reduction of molecular oxygen to water. Four protons are pumped across the inner mitochondrial membrane through CcO.

As pointed out by Cornwall and Tiktopoulos (CT) strong, time-varying electric fields may produce e+e- pairs in a resonant fashion. This effect could be related to the sharp peaks in the e+e- spectrum observed in the GSI heavy-ion collision experiments. We attempt to go beyond the case of spatially uniform fields discussed by CT. We find that resonant e+e- ...

High-resolution Fourier transform spectroscopy was used to record fluorescence progressions of KLi formed in a heat pipe. Lithium isotope effects were used to derive the adiabatic correction to the Born-Oppenheimer potential for the electronic ground state over a wide range of internuclear separations. With a short extrapolation from the experimentally determined potential functions of the coupled ...

Optical, electrical and discharge product measurements were performed in order to reveal the behaviour of N_2 ({A\\,^3\\Sigma_u^+}) metastables in a surface dielectric barrier discharge (DBD) driven in N2 with small NO admixtures in a modulated ac regime. Metastable species were detected both in a thin surface plasma layer and in the space afterglow ...

The effect of sulphide on resting oxidized cytochrome c oxidase was studied by both e.p.r. and optical-absorption spectroscopy. Excess sulphide causes some reduction of cytochrome a, CuA and CuB, and the formation of the cytochrome a3-SH complex after about 1 min. After several hours in the presence of excess sulphide only the e.p.r. signals due to ...

The RFQ is designed to accelerate ions with a minimum charge to mass ...

In this paper the non-linear interaction of a three-degrees-of-freedom structural model subjected to external excitation is examined. The non-linearity of the system results in different critical regions of internal resonance and this has a significant effect on the response. We use the method of multiple scales to determine a first-order uniform asymptotic expansion of the ...
