Superfamily: Spt6, helix-hairpin-helix domain

This superfamily entry represents the helix-turn-helix N-terminal domain (HTH) of Spt6 (Suppressor of Ty 6, originally discovered in Saccharomyces cerevisiae), a gene that influences general transcription through manipulation of chromatin structure at upstream promoter elements PMID:21419780.

Residues 933-1002 form two consecutive Helix-hairpin-Helix (HhH) motifs that pack together to form a (HhH)2 domain that resembles known dsDNA binding domains PMID:21419780.
