Table 2 The presence or absence of a complete shikimic acid pathway deduced from enzymes detected by HMM analysis in the predicted proteomes of 488 prokaryotes.

From: Global genome analysis of the shikimic acid pathway reveals greater gene loss in host-associated than in free-living bacteria

  Total Complete pathway Incomplete pathway % incomplete
Total 488 336 152 31

  1. As expected, nearly all of the 147 Bacteria that have never been reported previously to be associated with a host (termed 'free-living') contain a complete complement of enzymes forming this pathway.
