The S-layer of Bacillus sphaericus strain JG-A12, isolated from a uranium-mining site, exhibits a high metal-binding capacity, indicating that it may provide a protective function by preventing the cellular uptake of heavy metals and radionuclides.
Figure 4C presents the results of multiple binding and elution of QMC targets from the same QMC-coated magnetic beads, which demonstrate no significant changes in binding capacity indicating on reusability of QMC-beads.
The increase in binding affinity at lower pH was greater for the Ubx optimal binding site than for other DNA binding sites, indicating that subtle sequence alterations in DNA binding sites may influence pH-dependent behavior.
As compared with the wild-type Flag TAF15, the mutant Flag TAF15 K280P and Flag TAF15 G281S proteins showed about 54% and 64% reduced U1-binding capacities, respectively, indicating that the RNP1 motif contributes to the U1-binding capacity of TAF15.
Comparison of these proteins' in vitro binding sites with their in vivo binding sites indicates that PBM-derived specificitiesificanies caccuratelyely reflect in vivo DNA sequence specificities.
Epidermal growth factor (EGF) and GTPgammaS did not inhibit 125I-monitor peptide binding indicating that the binding sites are not EGF receptors or G protein-coupled receptors.
Closely related sequences in a related protein, adipophilin, did not confer Rab9 binding capacity to that protein.
These results are consistent with those reported in the literature (Thomas et al. 2012; Zibara 2001), except that the literature indicates lower binding capacities among specimens that contain silica fume.
The high binding capacity at low pH indicates that phosphate binding could begin in the stomach.
A MBP-fused MSTN1pro region consisting of residues 45 80 Pro45 800) also showed MSTN-inhibitory activity with a lower potency, and the Pro45 80 demonstrated its MSTN binding capacity in a pull-down assay, indicating that the MSTN-inhibitory capacity of Pro45 80 is due to its binding to MSTN.
