We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

| - | In early studies, two carboxylic acid binding sites, subsequently named A- and B-, were observed in the wild type crystal structure of fumarase C in ''E. Coli.'' The structures of these two sites was considerably different as site A contained atom of three of the four subunits of fumarase C whereas site B contained only atoms from a single subunit of the tetramer. | + | In early studies, two carboxylic acid binding sites, subsequently named A- and B-, were observed in the wild type crystal structure of fumarase C in ''E.

The structures of these two sites was considerably different as site A contained atom of three of the four subunits of fumarase C whereas site B contained only atoms from a single subunit of the tetramer. While it was heavily believed that the carboxylic acid binding site A- was the location of the fumarase active site, it could not be verified without first mutating both active sites in order to determine the activity of the reactions <ref>PMID:9098893</references> |
