Comparative analysis of human chromosome 22 CES-DGCR syntenic regions in chimpanzee, baboon, bovine, mouse and zebrafish and expression profiling in zebrafish early developmental stages using whole mount in situ hybridization.
(2006)
The final series of experiments were based on the earlier observation that 16 genes in the human chromosome 22 CES-DGCR region had reported expression but no detailed expression profiles while 6 others had no known expression ...
A study of the interactions of nitric oxide and nitric oxide containing molecules with heme proteins.
(2006)
The interactions of nitric oxide (NO), nitrite and organic nitroso compounds with heme proteins are biologically relevant. The formation of adducts between these NO-containing species and myoglobin (Mb) has served as a ...
Multiple species comparative analysis of human chromosome 22 between markers D22S1687 and D22S419 and gene expression profiling in zebrafish.
(2006)
Major large scale insertions or deletions that resulted in gene number differences between human and chimpanzee were discovered in the IGLL and LCR22s within this region, with four human insertions from 6 Kb to 75 Kb and ...
Site-directed mutagenesis as a probe to study the mechanism of sheep liver 6-phosphogluconate dehydrogenase.
(2006)
All mutant enzymes in the 2'-phosphate site exhibit an increase in KNADP that ranges from 6-fold to 80-fold. A 7-fold increase in the primary kinetic 13C-isotope effect minus 1 in all mutant enzymes indicates that the ...
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 ...
