binding sites

binding sites

1 concave features on antibody molecules that serve as locations for binding antigens. Because of possible variations in antibody amino acid sequences and molecule configurations, each kind of antibody can provide combining sites for a specific antigen.
2 locations on protein molecules where drugs or other substances may become bound by intermolecular forces or electrochemical attraction.

Therefore, in the present study, we isolated the bovine Nanog proximal promoter sequences which presumably contain evolutionarily conserved cis-regulatory sequences, including Oct4/Sox2, NF-[kappa]B, and Sp1 binding sites, and performed experiments in order to determine their roles in transcriptional activation of the bovine Nanog expression.
Using this method, the heat changes in the titration reaction process can be detected quantitatively and directly and the thermodynamic parameters such as binding constant K, number of binding sites (N), enthalpy change (H), entropy change (S) and Gibbs free energy (G) can be determined.
10) These data demonstrate that ZE2 and CD81 share similar binding sites on the P7 fragment of E2, but it needs further investigation
The regulatory machinery works when proteins called transcription factors bind to specific short sequences of DNA that flank the gene, called transcription factor binding sites, and by doing so, switch genes on and off.
C8[alpha] contains one or more lipid binding sites that become exposed within the MAC.
Because the actual binding sites were visualized, he believes that the MOF can be rationally designed to work even better.
The choline ends can occupy multiple choline binding sites of the CBP simultaneously.
We have used different site-specific probes to enhance our understanding of the drug-BSA interaction and thereby characterization of binding sites of the drugs used in the study on the BSA molecule (4,8,9,22,23).

More precise identification of the binding sites is currently being investigated by subjecting labeled peptide fragments to analysis by HPLC and mass spectrometry.
A disadvantage of conventional polymer imprinting is that each "antigen" or template molecule produces an artificial antibody containing all kinds of different binding sites, but most have poor recognition abilities and are therefore ineffective.
Distinctive hydration patterns for each of the quaternary structures were observed, but a number of conserved water molecule binding sites were found that are independent of the conformational state of the protein.
