This entry describes the C-terminal domain of the uncharacterized HTH-type transcriptional regulator PF0864, identified in the Pyrococcus furiosus archaea. The protein is 162 amino acids long and contains an HTH asnC-type domain (amino acids 6-78) responsible for DNA binding. The crystal structure of PF0864 (PDB: 2IA0) reveals a helix-turn-helix motif within the DNA-binding domain. The function and specific role of PF0864 in transcriptional regulation remain unknown.
