FIG. 2.

Cluster and operon arrangement of fla2 genes of R. sphaeroides. The arrows represent genes and their directions of transcription. When possible, gene designations were assigned on the basis of similarity with a gene having a known function. The lines and colors show the possible operon organization, using the criterion of a maximal distance of 30 bp between stop and initiation codons of two contiguous genes. Chromosome and plasmid localizations of the fla2 genes are indicated at the bottom.
