"The number of genes and genome length vary widely among prokaryotes: the smallest of the analyzed genomes, M.genitalium, had 517 predicted genes, whereas the largest one, M.loti, had 7596 predicted genes. The average gene density per 1000 nucleotides is close to 1.0 for almost all genomes, with the notable exception of M.leprae, in which massive gene decay has been discovered, resulting in numerous long spacers containing pseudogenes (ref 25). The fraction of non-coding DNA in the analyzed prokaryotic genomes varied from 5 to 50% (Table 1) however, for 90% of the genomes, the fraction of non-coding DNA was <18%, the major outliers being M.leprae and R.prowazekii, two genomes of bacterial parasites enriched in pseudogenes (ref 25–27)." Genmome size is 2,878kb. For 2,699 (2,711 including plasmids) protein coding genes see BNID 105499 Table - link |
