Crystallization/COMMENTARY
ORGANISM
UNIPROT
LITERATURE
crystal structure of Acl in its apo-form at a resolution of 0.97 A as well as in complex with CoA at a resolution of 1.59 A. The structures reveal that the enyzme belongs to a superfamily of proteins exhibiting a so called 'hot dog fold' which is characterized by a five-stranded antiparallel beta-sheet with a long alpha-helix packed against it
