Crystal structure of TmYeaZ (TM0874) from T. maritima. (a) Ribbon diagram of TmYeaZ monomer. Helices α1–α6 and β-strands β1–β9 are labeled. (b) A dimer of TmYeaZ consisting of two protomers in the asymmetric unit. (c) Alternate dimer formed by the crystallographic twofold axis. (d) Sequence alignment between TmYeaZ (PDB code 2a6a
), EcYeaZ (PDB code 1okj
) and StYeaZ (PDB code 2gel
). The secondary structure and sequence numbering of TmYeaZ are shown in the top row. The secondary structure of StYeaZ is shown in the bottom row. |
