Titanium dioxide photocatalyzed oxidation of proteins in biocontaminated waters.

• Lea Muszkat, Leonid Feigelson, L. P. Bir, Karol A Muszkat
• Journal of photochemistry and photobiology. B…
• 2001

The TiO2 photocatalyzed oxidation of the proteins serum albumin, ovalbumin and gamma globulin, is reported. All the amino acids were susceptible to photocatalytic oxidation. However, some were… (More)

Solar photo-inactivation of phytopathogens by trace level hydrogen peroxide and titanium dioxide photocatalysis

• Lea Muszkat, Leonid Feigelson, +5 authors G. Kirtzman
• Phytoparasitica
• 2008

Plant pathogenic bacteria in recirculated greenhouse water were inactivated by two distinct photochemical approaches: photo-inactivation in the presence of 0.005% to 0.01% hydrogen peroxide (H2O2),… (More)

Photocatalytic degradation of pesticides and bio-molecules in water.

• Lea Muszkat, Leonid Feigelson, L. P. Bir, Karol A Muszkat
• Pest management science
• 2002

Two approaches are suggested for the acceleration of the photocatalytic oxidation of organic contaminants of water: acceleration by oxidants and photo-enhancement by dyes. These processes were… (More)

Sub-second 2D NMR spectroscopy at sub-millimolar concentrations.

• Boaz Shapira, Erel Morris, Karol A Muszkat, Lucio Frydman
• Journal of the American Chemical Society
• 2004

A recently proposed protocol enables the acquisition of two-dimensional nuclear magnetic resonance (2D NMR) spectra within a single scan. A promising application opened up by this new data… (More)

Reactivities of tyrosine, histidine, tryptophan, and methionine in radical pair formation in flavin triplet induced protein nuclear magnetic polarization.

• Karol A Muszkat, T Wismontski-Knittel
• Biochemistry
• 1985

In order to check the validity of several basic assumptions of protein photochemically induced nuclear polarization (protein photo-CIDNP), we have investigated the quenching processes of the dye… (More)

CIDNP in tyrosyl protons of luliberin

• Karol A Muszkat, Chaim Gilon
• Nature
• 1978

WE report here on the possibility of extending CIDNP (chemically induced nuclear magnetic polarisation)-assisted NMR studies of the tyrosyl unit to medium sized peptides. Our previous studies… (More)

Photochemically induced nuclear polarization study of the accessibility of tyrosines in insulin.

• Karol A Muszkat, Igor Khait, Shulamith Weinstein
• Biochemistry
• 1984

The accessible tyrosines of bovine insulin were studied by the photochemically induced dynamic nuclear polarization (photo-CIDNP) method. Tyrosine 1H nuclear polarization is observed in acidic,… (More)

Effects of proteinase--inhibitor binding on accessibility of exposed tyrosines. A photochemically induced dynamic nuclear polarization study of bovine pancreatic trypsin inhibitor complexes with…

CIDNP study of the aromatic side chain interactions in myotoxin alpha.

• Karol A Muszkat, V A Preygerzon, Anthony T. Tu
• Journal of protein chemistry
• 1994

CIDNP and COSY measurements were applied to study aromatic side chain interactions and conformations in myotoxin alpha, a Crotalus venom toxin which acts as blocker of the Ca2+ influx in the… (More)

Studies on the biotin-binding sites of avidin and streptavidin. A chemically induced dynamic nuclear polarization investigation of the status of tyrosine residues.

• Geraldine M. Gitlin, Igor Khait, Edward A Bayer, Meir Wilchek, Karol A Muszkat
• The Biochemical journal
• 1989

We applied the protein photochemically induced dynamic nuclear polarization (photo-c.i.d.n.p.) method to explore the conformation of the side chains of tyrosine, tryptophan and histidine residues in… (More)
