These analogs serve as useful molecular probes to explore the secondary binding site, which can be exploited in designing more potent DAAO inhibitors.
The model indeed provided the structural rationale for its interaction with ligands and the cofactor and revealed unique characteristics of its binding site which could be exploited for improving the specificity of the inhibitors.
Among many other binding sites lost in the –673 construct were an E-box, a STAT binding site which forms a sequence model (Genomatix modelInspector) together with an ets binding site, and a Myc associated zinc finger binding site (MAZF).
Any binding site which had a p < 0.01 was annotated as a potential miRNA binding site.
When binding to DNA, LysR protein forms a homodimer and targets two specific binding sites, a regulatory binding site, which has the conserved T-N11-A/TTA-N7/8-GAA T-N11-A/TTA-N7/8-GAA T-N11-A/TTA-N7/8-GAA T-N11-A/TTA-N7/8-GAA T-N11-A/TTA-N7/8-GAAig. 2b).
The physiological relevance of this activity for PfCDPK1 is unknown; however, ATP hydrolysis by isolated kinases is not uncommon and is considered to be a function of the ATP-binding site, which can be exploited for identification of inhibitors (27).
In the previous experiments we could identify three lectins with opposing binding sites which are able to crosslink adjacent vesicles.
The PACAP specific binding sites which were not shared VIP were termed type I, while the binding sites shared with both PACAP and VIP were termed Type II.
The sequence of this binding site does not resemble any known ATP binding sites, which have much higher binding affinities.
By building towards the less polar cofactor binding site and exploiting additional interactions with the enzyme it should be possible to improve their affinities.
