Statistics for the Matches of the 4241 E. coli Genes used as Queries Against the Target Genomes Given in the Column Heading

Number of: eco stm kpn ype vch
All matches 5987 4429 4497 3103 2285
orfs with ≥1 match 4241 3250 3047 2425 1695
Unique matches 3414 2567 2301 2013 1385
Orth. upstream regions 2574 1928 1752 1424 936

  • The first row counts all distinct matches in the target; the second row gives the number of queries with a valid match; the third row counts how many of the 4241 queries had a unique match within our threshold (score <10−25 and percent identity over 40%); and the last row are all those unique matches that have at least 50 bases upstream that do not overlap coding sequence on either strand. There are 2127 E. coli genes that have orthologous upstream region in at least one organism, and 768 genes with an orthologue in all four species.
