5.1.3.22 | protein has a triosephosphate isomerase barrel fold and forms dimers. The active site is located at the C-terminal ends of the parallel beta-strands. The enzyme binds Zn2+, which is coordinated by Glu155, Asp185, His211, and Glu251. A phosphate-binding site is formed by residues from the beta1/alpha1 loop and alpha3'-helix in the N-terminal region |
