'''CRYSTAL STRUCTURE OF MUCONOLACTONE ISOMERASE AT 3.3 ANGSTROMS RESOLUTION'''<br />


==Overview==
==CRYSTAL STRUCTURE OF MUCONOLACTONE ISOMERASE AT 3.3 ANGSTROMS RESOLUTION==
The crystal structure of muconolactone isomerase from Pseudomonas putida, a unique molecule with ten 96 amino acid subunits and 5-fold, and 2-fold, symmetries, has been solved at 3.3 A resolution. The non-crystallographic, symmetries were used to refine the initial single isomorphous replacement, phases and produce an interpretable 10-fold averaged map. The backbone, trace is complete and confirmed by the amino acid sequence fit. Each, subunit is composed of a body with two alpha-helices and an antiparallel, twisted beta-sheet of four strands, and an extended arm. The helices and, the sheet fold to form a two-layered structure with an enclosed, hydrophobic core and a partially formed putative active site pocket. The, C-terminal arm of another subunit related by a local dyad symmetry extends, over the core to complete this pocket. The decameric protein is almost, spherical, with the helices forming the external coat. There is a large, hydrophilic cavity in the center with open ends along the 5-fold axis., Molecular interactions between subunits are extensive. Each subunit, contacts four neighbors and loses nearly 40% of its solvent contact area, on oligomerization.
