TopicPage for Non-Core971 of Escherichia coli K-12


CommonCore-5         

Description:

Non-Core971 is a set of 971 sequences including 908 genes and 63 pseudogenes that are not common to five E. coli strains (Davids, 2008). These include strain- and lineage-specific genes but the horizontally transmitted HT, prophage and IS genes have been removed from Non-Core971 by Davids (2008) or EcoGene..

Details:

Using a gene by gene similarity comparison of five genomes and codon correspondence analysis, Davids (2008) identified and then refined three non-overlapping gene sets as core (2158 genes), non-core (1044 genes), and HGT (HT, 1053 genes).
