FIG. 4.

Operon map of sequenced genes. Solid lines with arrowheads indicate sequenced portions of each ORF, drawn to scale. The amino acid length of each ORF is indicated, without parentheses for completed sequences and with parentheses for incomplete sequences. The positions of key degenerate primers used to amplify the ORFs are indicated by vertical lines below small, labeled arrowheads. Paralog names and group numbers are indicated above the appropriate ORFs. Genus, species, and strain designations for each ORF are indicated at the right. GenBank accession numbers are given in braces.
