FIG. 1.

Alignment of predicted catalytic domains of deformylase. Three conserved motifs that define the catalytic domain of deformylase are shown. The positions of the motifs in the E. coli protein are as follows: box 1, G44 to Q51; box 2, E89 to S93; box 3, Q132 to G140. An asterisk next to a bacterial name indicates the presence of an fmt homolog downstream of the def homolog. Those residues that diverge from the consensus sequence are highlighted.
