A mathematical description of multi-ligand binding to a single binding site is presented for both the continuously and transiently accessible cases.
The Gal binding site is presented in all the four GI NoVs whose structures of the HBGA binding interfaces are known and two of their amino acid compositions (Asp and Ser) are conserved among GI genotypes (Figs. 1 and 6).
Our previous laser flash photolysis studies provided a direct determination of the kinetics of the FMN-heme IET in a truncated two-domain construct (oxyFMN) of murine inducible NOS (iNOS), in which only the oxygenase and FMN domains along with the calmodulin (CaM) binding site are present (Feng et al. J. Am. Chem. Soc. 128, 3808-3811, 2006).
The small dashed-lines denote un-fixed conformation, where the base position belonging to this region can be either paired or unpaired as long as other mandatory regions (i.e., the base pairing of CUGAUGAG-region and the complementary half of the helix II, effector 1 (E1) with its binding site and effector 2 (E2) with its binding site) are present.
Sequences similar to the DmTTF binding site are present in all of the Brachycera and some of the Nematocera but is notably absent from the mosquitoes.
If enough substitutions in each type of binding site are present, the test above can be performed for each type, and then their results can be combined.
To note, several auxin-responsive elements (AuxRE), such as the Auxin Response Factor (ARF) binding site and the Small Auxin-Up RNA (SAUR) binding site are present in the MIR168 promoter.
In some cases, these structures were labelled also with fluorescent cAMP (Fig. 2F): this suggests that complex structures containing both PKA catalytic subunit and a peculiar cAMP binding site, are present in MB tissue.
