STRUCTURE OF A HAP1-18/DNA COMPLEX REVEALS THAT PROTEIN/DNA INTERACTIONS CAN HAVE DIRECT ALLOSTERIC EFFECTS ON TRANSCRIPTIONAL ACTIVATIONSTRUCTURE OF A HAP1-18/DNA COMPLEX REVEALS THAT PROTEIN/DNA INTERACTIONS CAN HAVE DIRECT ALLOSTERIC EFFECTS ON TRANSCRIPTIONAL ACTIVATION

Structural highlights

2hap is a 4 chain structure with sequence from Saccharomyces cerevisiae. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.5Å
Ligands:
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

HAP1_YEASX Regulation of oxygen dependent gene expression. It modulates the expression of Iso-1 (CYP1) and Iso-2 (CYP3) cytochrome c. In response to heme, promotes transcription of genes encoding functions required for respiration, controlling oxidative damage and repression of anaerobic genes. Binds to the sequence 5'-CGGNNNTNNCGG-3'. Is non-functional in terms of iso-1 cytochrome c expression in strain S288c and its derivatives.[1] [2] [3] [4]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
