Enzyme structure and function pot

... analyzed. Only two structures with repeated y and f angles are commonly found in proteins: the right-handed a-helix and the b-pleated sheet. As enzymes are generally relatively compact structures and a-helixes ... very little space is left between the protein and the ligand and only part of the ligand is exposed to the solvent. The close packing of enzyme and ligands is illustra...

Both NFAT and AP-1 have the potential to recruit the HATs CBP and p300 which may ... enhanceosomes. AP-1, and potentially NFAT, are also able to recruit SWI ⁄ SNF family complexes which most probably contribute to both the disruption and ejection of nucleosomes within...
