Various biochemical affinity purification methods provide direct approaches to discover target proteins binding small molecules of interest for this purpose [3 6].
It shares some of the biochemical properties of CFH, including affinity for C3b and for glycosaminoglycans on host cell surfaces (this can be estimated in the laboratory by measuring affinity for the glycosaminoglycan heparin).
However, recent biochemical studies show that NikR's affinity for DNA is also dependent on potassium (8), and calculations examining metal stability, charge, and size preference suggest that these second metal binding sites are optimized for potassium binding (7).
Our computational model was supported by biochemical data showing a decrease in affinity for a Src mutant with changes in the protein substrate binding site and synergistic inhibition when combined with ATP-competitive inhibitors.
The difference between the values obtained in the presence of either NR2A or NR2B using ITC are similar to the observations made in biochemical studies with NR2B inducing a higher affinity for the nucleotide binding (Fig. 1) [8].
Among the currently available bisphosphonates with different mineral binding and biochemical actions, risedronate has a comparatively lower affinity for bone mineral [29,30], which may facilitate its access to the mechano-responsive cells of the osteocytic lacunar network [31].
53a In addition to the photophysical properties of sensors (brightness, photostability, wavelength range) and biochemical properties (affinity and specificity for the target metal), there are a number of factors that influence the use of fluorescent sensors for mapping accessible pools of metal ions in cells.
Biochemical studies have suggested that GSIIB has a lower affinity for NH4 + and Glu than GSIIE [ 42], characteristics that would be advantageous for enzymes assimilating higher concentrations of NH4 + from environmental sources, NO3 - assimilation, or increased rates of photorespiration.
Biochemical studies revealed that Medea - dSno complexes have reduced affinity for Mad and increased affinity for dSmad2 such that in the presence of dSno, Activin signaling is stimulated and Dpp signaling is reduced.
Further study showed that the biochemical functions of MCM, including ATP hydrolysis, helicase activity and affinity for DNA substrates, are increased markedly upon association with both Cdc45 and GINS (Ilves et al. 2010).
