TL;DR: The genome of Rhodobacter capsulatus has been completely sequenced and unusual features include the presence of numerous cryptic phage genomes embedded in the chromosome.
Abstract: The genome of Rhodobacter capsulatus has been completely sequenced. It consists of a single chromosome containing 3.5 Mb and a circular plasmid of 134 kb. This effort, started in 1992, began with a fine-structure restriction map of an overlapping set of cosmids that covered the genome. Cosmid sequencing led to a gapped genome that was filled by primer walking on the chromosome and by using lambda clones. Methods had to be developed to handle strong stops in the high GC (68%) inserts. Annotation was done with the ERGO system at Integrated Genomics, as was the reconstruction of the cell's metabolism. It was possible to recognize 3709 orfs of which functional assignments could be made with high confidence to 2392 (65%). Unusual features include the presence of numerous cryptic phage genomes embedded in the chromosome.

TL;DR: A comparative analysis of electrostatic potential distribution for "early" T4 phage promoters was undertaken and it is indicated that there are some particular elements in the patterns of electro static potential distribution of promoter DNA specific for promoter groups differing by their functional response to ADP-ribosylation of the alpha-subunit as well as to rpoB403- or rPOB409 mutationals of the beta-sub unit of RNA-polymerase.
