Revised sequence and annotation of the Rhodobacter sphaeroides 2.4.1 genome.

The DNA sequences of chromosomes I and II of Rhodobacter sphaeroides strain 2.4.1 have been revised, and the annotation of the entire genomic sequence, including both chromosomes and the five plasmids, has been updated. Errors in the originally published sequence have been corrected, and ~11% of the coding regions in the original sequence have been affected by the revised annotation.
