Figure 5. The structure and function of MDH.

Figure 5

A) The relative enzyme activities of MDH and its variants. Mean values and standard deviations were calculated from three replicates. The enzyme activity of wild-type MDH was set as 1. B) The crystal structure of E. coli MDH tetramer (PDB ID: 3HHP). C) A zoom-in view of the dimer-dimer interface. D) A map of amino acids involved in the dimer-dimer interface.
