FIG. 5.

Alignment of the PRD-I and -II domains from the YdaA, LicR, and YjdC proteins from B. subtilis (Bs); the MtlR protein from B. stearothermophilus (Bt); and the SrlR proteins from S. mutans LT11 (Sm). Identical residues present in all domains at positions 14 and 61 are boxed, positions with similar residues in at least five domains are indicated by a period, and positions with identical residues in at least five domains are indicated by an asterisk. Positions 7, 14, 61, and 69 of the alignment (see text) are indicated at the top.
