Binding of Oxygen and Carbon Monoxide to a Heme-regulated Phosphodiesterase from Escherichia coli
The heme-regulated phosphodiesterase, Ec DOS, is a redox sensor that uses the heme in its PAS domain to regulate catalysis and the kinetics of CO binding to the isolated PASdomain and its mutants are similar to those observed for O2. Expand
Fabrication of ZnPc/protein nanohorns for double photodynamic and hyperthermic cancer phototherapy
It is concluded that carbon nanotubules may be a valuable new tool for use in cancer phototherapy. Expand
Efficiency of singlet oxygen production from self-assembled nanospheres of molecular micelle-like photosensitizers FC4S
Direct detection of singlet oxygen (1O2) production under irradiation of molecular micelle-like hexa(sulfo-n-butyl)[60]fullerene (FC4S) self-assembled nanospheres at 500–600 nm was obtained by theExpand
Distance dependence of electron transfer in acridine-intercalated DNA
Abstract The photoinduced electron-transfer reaction in a DNA helix has been studied using 9-amino-6-chloro-2-methoxyacridine (ACMA) selectively intercalated at an internucleotide site of a DNA. TheExpand
Supramolecular donor-acceptor hybrids of porphyrins/phthalocyanines with fullerenes/carbon nanotubes: electron transfer, sensing, switching, and catalytic applications.
Extension of the self-assembly approaches to single wall carbon nanotubes results in SWNT-porphyrin/phthalocyanine nanohybrids capable of undergoing photoinduced electron transfer. Expand
Energy transfer followed by electron transfer in a supramolecular triad composed of boron dipyrrin, zinc porphyrin, and fullerene: a model for the photosynthetic antenna-reaction center complex.
The first example of a working model of the photosynthetic antenna-reaction center complex, constructed via self-assembled supramolecular methodology, is reported, and it is reported that the important feature of the present model system is its relative "simplicity". Expand
Supramolecular carbon nanotube-fullerene donor-acceptor hybrids for photoinduced electron transfer.
The present nanohybrids were further utilized to reduce hexyl-viologen dication and a sacrificial electron donor, 1-benzyl-1,4-dihydronicotinamide, in an electron-pooling experiment, offering additional proof for the occurrence of photoinduced charge-separation and potential utilization of these materials in light-energy harvesting applications.

Sensitive efficiency of photoinduced electron transfer to band gaps of semiconductive single-walled carbon nanotubes with supramolecularly attached zinc porphyrin bearing pyrene glues.
The present nanohybrids were further utilized to photochemically reduce the hexyl viologen dication in the presence of a sacrificial electron donor in an electron-pooling experiment, offering additional proof for the occurrence of photoinduced charge separation and potential utilization of these materials in light-energy-harvesting applications.

CO binding studies of engineered cytochrome P-450ds: effects of mutations at putative distal sites in the presence of polycyclic hydrocarbons.
It was suggested that phenanthrene and anthracene distort the Fe-C-O bond and/or affect the access of CO to wild-type P-450d in an opposite way from 1,2:3,4-dibenzanthracene and 7,8-benzoflavone. Expand
Conserved Glu at the Cytochrome P450 1A2 Distal Site Is Crucial in the Nitric Oxide Complex Stability (*)
It is suggested that the NO-ferric complex stability of P450, and perhaps of NOS, is largely ascribed to an ionic bridge between NO and the distal carboxyl group. Expand
