... DNA-binding domain (DBD) at the amino-terminus and the oligomerization domain in the central region of the protein [1,4]. The HSF DBD belongs to the ‘winged’ helix-turn-helix family of DNA-binding ... interactions. In HSF DBD– HSE co-crystals, the protein–protein interface consists of the helix 2 amino-terminus, the turn and the wing [15]. Unlike other winged helix-turn-helix protei...
