Fig. 1

Genomic map of E. coli strain LCT-EC001. From outer to inner in a, the first circle shows the identified genes in LCT-EC001. The 2nd–4th circles show the COG, KEGG, and GO functions of these identified genes, respectively, and each color represents a function classification in which details are annotated in e, d, and b, respectively. The 5th circle shows the ncRNA results, and each color represents a classification in which details are annotated in c. For these five circles, the outer side of each represents a positive strand, while the inner side represents a negative strand. The 6th circle shows the GC contents. The 7th circle represents the LCT-EC001 GC-skew distribution. GC-skew = (G − C)/(G + C); purple and green indicate positive and negative values, respectively
