'''THE 1.8 ANGSTROM CRYSTAL STRUCTURE OF THE DIMERIC PEROXISOMAL THIOLASE OF SACCHAROMYCES CEREVISIAE'''<br />


==Overview==
==THE 1.8 ANGSTROM CRYSTAL STRUCTURE OF THE DIMERIC PEROXISOMAL THIOLASE OF SACCHAROMYCES CEREVISIAE==
The dimeric, peroxisomal 3-ketoacyl-CoA thiolase catalyses the conversion, of 3-ketoacyl-CoA into acyl-CoA, which is shorter by two carbon atoms., This reaction is the last step of the beta-oxidation pathway. The crystal, structure of unliganded peroxisomal thiolase of the yeast Saccharomyces, cerevisiae has been refined at 1.8 A resolution. An unusual feature of, this structure is the presence of two helices, completely buried in the, dimer and sandwiched between two beta-sheets. The analysis of the, structure shows that the sequences of these helices are not hydrophobic, but generate two amphipathic helices. The helix in the N-terminal domain, exposes the polar side-chains to a cavity at the dimer interface, filled, with structured water molecules. The central helix in the C-terminal, ...
