Has a chain structure with 2.4 A resolution, and 2.9 A resolution with a co-factor (acetyl-CoA). The method used to determine the structure was X-ray crystallography. | Has a chain structure with 2.4 A resolution, and 2.9 A resolution with a co-factor (acetyl-CoA). The method used to determine the structure was X-ray crystallography. Sedimentation and crystal structure analysis clearly shows that Hpa2 is dimeric in solution and tetramerizes in the unit crystal. The average B-factor value is 23.9 (main chain) with a 25.4 side chain. The R-factor is 0.19. | ||

Most of the secondary structure elements of the monomer contribute residues in dimer contacts. They form a barrel-like with ten strands in which the component strands of the barrel are locked together. | Most of the secondary structure elements of the monomer contribute residues in dimer contacts. They form a barrel-like with ten strands in which the component strands of the barrel are locked together. There are eight beta-strands, four alpha-helices, and ten turns. | ||
