Circular map of N. lactamica Y92–1009 genome and features generated with Cgview Comparison Tool. The arrows in the outermost ring indicate putative genes (with the arrow indicating the 5′ to 3′ direction on the positive strand.) identified and assigned to Clusters of Orthologous Groups (COGs). The 20 COG categories are indicated by different colours from Red to Grey according to the colour key. The second and third rings indicate regions containing coding sequence (Blue), tRNA (Orange), and other RNAs (Grey), with the second ring running 5′ to 3′ (positive strand) and the third ring running 3′to 5′ (negative strand). The fourth ring indicates open reading frames assigned as COGs and encoded on the negative strand. The fifth, black, graph ring displays GC content while the last ring (purple and green) shows positive (Green) and negative (Purple) GC skew
