STRUCTURE OF TRANSCRIPTION FACTOR GENESIS/DNA COMPLEX
OverviewOverview
Genesis is an HNF-3/fkh homologous protein. By using multi-dimensional NMR techniques, we have obtained the solution structure and backbone dynamics of Genesis complexed with a 17 base-pair DNA. Our results indicate that both the local folding and dynamic properties of Genesis are perturbed when it binds to the DNA site. Our data show that a conserved flexible amino acid sequence (wing 1) makes dynamic contacts to DNA in the complex and a short helix is induced by Genesis-DNA interactions. Our data indicate that, unlike the HNF-3gamma/DNA complex, a magnesium ion is not required in forming the stable Genesis-DNA complex.
