enzyme TtHSD folds into a dimer with a noncrystallographic 2fold axis. The subunit comprises three conserved domains of HSDs and a flexible tail at the C-terminus. The nucleotide-binding domain (residues 1-119 and 288-309) assumes an alpha/beta Rossmann fold with five beta-strands and four alpha-helices. The dimerization domain (residues 120-140 and 261-287) comprises two alpha-helices and two beta-strands that interact with the corresponding domain of the other subunit of the dimer to form an alpha/beta structure with the four-stranded beta-sheet. The substrate-binding domain (residues 141-260) comprises four beta-strands and five alpha-helices. The flexible tail at the C-terminus (310-332) extends from the nucleotide-binding domain to the substrate-binding domain |
