Gene organization in the cmp genomic region of Synechocystis sp. strain PCC 6803 and construction of insertional mutants of the cbbR homologs. (A) Map of the cmp region of the genome of Synechococcus sp. strain PCC 7942 and Synechocystis sp. strain PCC 6803, showing the extent of identity of the deduced amino acid sequences of the corresponding cmp genes. (B) Structure of the sll0030 genomic region of the MR1 and MR12 mutants and that of the sll1594 genomic region of the MR2 and MR12 mutants of Synechocystis sp. strain PCC 6803. The gene organization in Synechocystis was obtained from Cyanobase (http://www.kazusa.or.jp/cyano/cyano.html). The cmp genes are indicated by stippled bars, and the cbbR homologs (sll0030 and sll1594) are indicated by filled bars. Open bars represent the antibiotic resistance gene cassettes, with hatched bars showing the locations and orientations of the kanamycin resistance gene (npt) and the spectinomycin resistance gene (aad). Abbreviations for restriction endonuclease sites: B, BglII; E, EcoRV; N, NheI; D, DraI.
