Figure 2
Multiple sequence alignment of fuculose aldolases from G. antarctica (PDB entry 4xxf), P. syringae (PDB entry 3ocr), B. thetaiotaomicron (PDB entry 2opi), A. aeolicus (PDB entry 2irp), T. thermophilus (PDB entry 2flf), E. coli (PDB entry 2fua) and S. pneumoniae (PDB entry 4c24). Residues that are strictly conserved (white letters on a red background) and conservatively substituted (black letters on a yellow background) are boxed. Histidine-triad residues are marked below the alignment with blue stars. One of the histidine residues for PDB entry 2opi has been replaced by a glutamine, whereas the other fuculose aldolases have conserved histidine-triad residues. |
