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 ...
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 ...
Stressed Out: Resistance-nodulation-division (RND) and Major Facilitator Superfamily (MFS) Efflux Pump Mediated Survival Strategies of Acinetobacter baumannii
(2024-05-11)
Originally discovered in soil microbial communities, reports of genus Acinetobacter associated infections started to increase around 1977 and continued to climb to frightening heights for the next 20 years resulting in ...
