Iron uptake in Gram-negative and Gram-positive bacteria.
(2006)
Bacteria, including both Gram-positive and Gram-negative bacteria, utilize iron sources from the environment. Iron uptake systems in Gram-negative bacteria are well studied. Escherichia coli FepA transports certain catecholate ...
Binding and transport through ferric siderophore receptors, FepA and FhuA.
(2006)
Under iron deficient conditions, Gram-negative bacteria like E. coli secrete siderophores to chelate iron in the extracellular medium. Ligand-gated porins (LGPs) transport the ferric siderophore complexes across the outer ...
Halogens, taurobetaine and waxes in gorgonians /

Evaluation of toxic metals in natural fish populations in Oklahoma.
(1981)
The level of toxic metals was low in the water samples but were much higher in the sediment samples. There were no significant correlations beween the levels of toxic metals in the water to the levels in the sediment.
An investigation of protein-nucleic acid interactions :
(1984)
I have investigated the formation of the aa-tRNA*EF-Tu*GTP ternary complex spectroscopically by monitoring a fluorescence change which accompanies the association of EF-Tu*GTP with Phe-tRNA('Phe)-F('8), a functionally ...
A bioinorganic approach to the study of the interactions of nitrogen oxides with manganese porphyrins and manganese- and cobalt-reconstituted myoglobin.
(2007)
This dissertation deals with the interaction of the biologically important nitrogen oxides (nitric oxide and nitrite) with manganese and ruthenium centers in small inorganic porphyrin and nonporphyrin complexes as well as ...
Uptake, localization, and fate of tritiated arginine in Haematoloechus medioplexus (Trematoda) /
