FIG. 3.

Alignment of the deduced primary sequences of R. meliloti BdhA, the putative oxidoreductase, YxjF from B. subtilis (51), and Bdh from Rattus norvegicus (20). The position of cleavage of the mitochondrial targeting sequence of the Rat Bdh is marked by an arrow. The amino acid residues involved in coenzyme binding are indicated by asterisks. The amino acid residues corresponding to the proposed consensus for SCAD are indicated by a broken hatched overline. The six strictly conserved residues are indicated by solid circles below the residues. The seven other conserved residues common to most members of the SCAD superfamily are highlighted by carets under the residues. Alignment was performed by using the ClustalW program.
