| - | The SCP2-thiolase is a member of the thiolase family of enzymes. It has low sequence identity with any of the other thiolases. Like many other thiolases it is a dimer in solution. In the 6HSP crystal structure there are two monomers per asymmetric unit. One monomer forms the classical dimer with a two-fold related symmetry mate. The other monomer has a different packing and it is not forming the classical dimer: its structure is the structure of the monomer. There are large structural differences between these two monomers. The comparison of the structures of the "dimerised" monomer and the single monomer visualises the structural changes that happen when the single monomer dimerises to form the mature dimer. | + | The SCP2-thiolase is a member of the thiolase family of enzymes<ref>PMID:24825023</ref>.
