The crystal asymmetric unit was found to contain <scene name='69/694235/3log/1'> four MbtI molecules</scene>, however crystal packing and size exclusion chromatography data suggest a monomeric enzyme. There are no significant structural changes between the four monomers excepts from the localized differences in the active site | The crystal asymmetric unit was found to contain <scene name='69/694235/3log/1'> four MbtI molecules</scene>, however crystal packing and size exclusion chromatography data suggest a monomeric enzyme. There are no significant structural changes between the four monomers excepts from the localized differences in the active site <ref name= "3a"> DOI:10.1128/JB.0038-06</ref>. The overall molecular structure consist of a polypeptide of 450 residues that forms one large single domain with a similar fold to other chromate-utilizing enzymes (3). The core of the protein is formed by 21 <scene name='69/694235/Beta_sheets/3'>beta-strands</scene> folded into a twisted beta-sandwich. The protein's core is then surrounded by <scene name='69/694235/Beta_sheets/4'>10 alpha helices</scene>(3). | ||
