Crystal structure of TTHA0849 from Thermus thermophilus HB8
Overview
The crystal structure of a conserved hypothetical protein, TTHA0849 from Thermus thermophilus HB8, has been determined at 2.4 A resolution as a part of a structural and functional genomics project on T. thermophilus HB8. The main-chain folding shows a compact alpha+beta motif, forming a hydrophobic cavity in the molecule. A structural similarity search reveals that it resembles those steroidogenic acute regulatory proteins that contain the lipid-transfer (START) domain, even though TTHA0849 shows comparatively weak sequence identity to polyketide cyclases. However, the size of the ligand-binding cavity is distinctly smaller than other START domain-containing proteins, suggesting that it catalyses the transfer of smaller ligand molecules.
