Figure 5From: Structure and functional characterization of pyruvate decarboxylase from Gluconacetobacter diazotrophicusModel of the water tunnel connecting the two active sites in a GdPDC dimer. Water molecules are shown as red spheres. Residues lining the water tunnel are shown as stick models in dark green and labeled. The carbon atoms in the pyrimidine rings of the ThDP cofactor molecules are colored red and nitrogen in blue.Back to article page
