Moessbauer Studies of Photosynthetic Reaction Centers From Rhodopseudomonas Sphaeroides R-26
… detergent, oxidation state, or the presence of o-phenanthroline all show a single quadrupole doublet of similar splitting (DELTA)E(,Q), center shift (delta), and temperature dependence. The results are indicative of high-spin ferrous iron (Fe('+2), S = 2) with an approximately invariant first …

Mössbauer studies of photsynthetic reaction centers from Rhodopseudomonas sphaeroides R-26
… detergent, oxidation state, or the presence of o-phenanthroline all show a single quadrupole doublet of similar splitting 6EQ, center shift 0, and temperature dependence. The results are indicative of high-spin ferrous iron (Fe+2, S=2) with an approximately invariant first coordination sphere …

Kinetics of electron transfer and binding of inhibitors in the two-electron gate of chloroplasts
… of the inhibitors, e.g. DCMU, atrazine, o-phenanthroline, cyanoacrylate derivatives, naphthoquinone analogues.

The Effect of Seed Sprouting Time and Light on Phytic Acid Concentration
… samples was determined colorimetrically using o-phenanthroline according to the method described in AOAC.</p> <p>The results of the study showed a significant decrease of phytic acid by the end of the allotted sprouting time for all types of sprouts grown without light. The decrease in phytate …

Single cell gel electrophoresis-based investigations of UVR- and visible light-induced single strand breakage in cultured human cells
… responses were modulated by beta-carotene and o-phenanthroline; these molecules appeared to have both photosensitising and photoprotective properties, in the cells tested at least. Inorganic arsenic (V) was observed to inhibit single strand break repair and the religation of repair-related …

Production, purification and properties of Bacillus thuringiensis neutral protease
… to metal chelating agents such as EDTA and O-phenanthroline. The molecular weight of the neutral protease has been estimated to be about 37,000 by electrophoresis in SDS-polyacrylamide gels. In the presence of 0.1% calcium acetate, the enzyme is quite stable at 60 C after 10 minutes …

Studies of the nature of Burkholderia cepacia in cystic fibrosis
… ethylene diamine tetra acetic acid and o-phenanthroline was reversed by addition of zinc, indicating a metallo-enzyme, whilst >90% inhibition was attainable with 0.1mM concentrations of tazobactam and clavulanic acid. A study of 8 other clinical isolates showed an enzyme of pI 8.45 to be …

An extracellular protease from an extreme thermophile
… to EDTA, EGTA, and iodoacetic acid, but not o-phenanthroline or p-chloromercuri benzoate, were noted. Together with the presence of lytic activity (Caldolysin lysed a broad range of Gram-negative bacteria but only few Gram-positive organisms), this permitted the classification of Caldolysin as …
