Comparison of genetic organization between PCN033 and PCN061. a Complete genomic structure comparison between PCN033 and PCN061. The graph represents an alignment of the colinear blocks, identified by MAUVE, that shared in the two genomes. Each sequence of identically colored blocks represents a collinear set of matching regions. One connecting line links per collinear blocks. Arrows points out the unique regions of PCN033 and PCN061. GI means genomic island. PR means prophage region. RM means restriction-modification system. FB means fimbrial biosythesis. CPS means capsular polysaccharide synthesis. b Comparison of gene clusters for O-antigen polysaccharide synthesis between PCN033 and E. coli O11 G1207, PCN061 and E. coli O9 F719. Arrow represents predicted ORF. Gray arrow represents hypothetical protein gene. Green arrow represents “housekeeping” genes identified as reference. Yellow rectangle represents IS element. Homologous genes in different strains are linked by lines. Black number near by the connecting line means the nucleotide similarity between homologous genes (100 %). Red number means amino acid similarity between homologues (100 %). PBP: polysaccharide biosynthesis protein. GT: glycosyltransferase. TA: tyrosine autokinase. APH: acid phosphatase homologues. PEP: polysaccharide export protein
