Figure 8

Superimposition of active site residues coordinated to the two metal ions and residues around the butyrate ion in Pmi1525 and homologous residues near the DTT bound in the active site of Rsp3690. The residues of Pmi1525 are colored in light gray; the residues of Rsp3690 are colored in cyan and the residue labels are enclosed in brackets. The carbon chain of butyrate bound in the active site of Pmi1525 is shown in green and the carbon chain of DTT bound in Rsp3690 is shown in orange. Manganese atoms are colored pink and the zinc atoms are colored in dark grey. Oxygen is shown in red and sulfur in yellow.
