• PubMed Abstract: 
  

  Reinterpretation of the space-group symmetry is reported for two crystal structures of Candida albicans 3,4-dihydroxy-2-butanone 4-phosphate synthase (PDB codes 1tks and 1tku). The two structures reported in space group P1 with a dimer in the asymmetric unit can be described as C-centered monoclinic structures with one subunit in the asymmetric unit.
