Highly selective ion discrimination should occur when binding sites form rigid cavities that match K+, but not the smaller Na+, ion size or when binding sites are composed of specific chemical groups.
GAGA-factor binding sites are composed of either two or more GAG trinucleotides, or else a GA repeat of five or more bases, neither of which are present in the 12 0 sequence, therefore we concluded that 12 0 is not likely to be a GAGA-factor binding site [ 23].
Each of the antigen-binding sites was composed of a single-chain Fv (ScFv).
Then the binding site is composed of residues within 10 Å from the ligand (Fig. 4b).
The binding site is composed of residues (green) within 8 Å from the ligand (red).
And the binding site is composed of residues (green) within 10 Å from the ligand (red), which is different from 8 Å for bound chain prediction.
For bound chain (such as PDB ID: 5p2p, CHAIN ID: A), the binding site is composed of residues within 8 Å from the ligand (Fig. 4a).
The primary binding site is composed of pyrimidine-specific binding clefts that are located in the N-terminal domains and anchor Rho to transcripts at C-rich Rut (Rho utilization) sites.
These results support the idea that a strong SNF binding site is composed of two U-run sequences, even if they are separated by more than 10 bases.
The outer binding site is composed of HBP1 and HBP1', formed primarily by residues Lys15, Leu17, Thr106, and Val121 of both subunits.
The genes of a receptor's binding site are composed individually by rearranging short pieces of DNA.
