In many cases, the specific small molecules that bind to the regulatory sites have no obvious structural similarity to the substrates of the enzymes; these small molecules are therefore termed allosteric effectors, and the regulatory sites are termed allosteric sites.
Interactions with the appropriate molecules at these regulatory sites cause changes in the shape of the enzyme molecule.
Furthermore, EBF1 binding to Gata3 regulatory sites induced repressive histone modifications across this region.
Examples of the application of this methodology to identify metabolic bottlenecks and regulatory sites are presented.
The promoter fragment was chosen to include the main regulatory sites required for functional control of transcription.
Thus, binding at genuine regulatory sites on DNA would be optimized by locally increasing the concentration of multimeric transcription factors.
Moreover, phosphorylation levels for numerous regulatory sites in these pathways were significantly changed due to PPP1R12A knockdown.
There are marked differences in nucleosome and coregulator composition at different classes of HIRA-bound regulatory sites.
Using the advantage provided by amphiphilic ligands, here we explore a new approach for determining hidden regulatory sites.
This requires the development of creative approaches to identify novel transcriptional regulatory sites in the genome.
The majority of these binding sites are likely to represent bona fide regulatory sites.
