Fig 1. Organization of the AFI gene cluster and yfdX in E. coli MG1655 and K. pneumoniae CG43, NTUH-K2044, and MGH78578.

Fig 1

The genes were annotated according to the National Center for Biotechnology Information (Version 3.20.3) using BLASTX analysis. In E. coli MG1655, the cluster of genes from slp to gadA has been designated as an acid fitness island (AFI). The genes yfdX, hdeDB, and hdeB1 were found in all three K. pneumoniae genomes, whereas hdeA was identified only in the CG43 genome. The cluster of genes from kvgS1 to kvhR was found in CG43 genome but not in the genome of NTUH-K2044 and MGH78578.
