Computing prokaryotic gene ubiquity: Rescuing the core from extinction

Table 5.

Prevalent genes computed from cross-phylum analysis


A: ubiquitous genes (total 34):
argS infB pheS rplN secY
dnaG ksgA proS rpsB serS
dnaX leuS rplA rpsC thrS
fusA lysS rplC rpsD trpS

  • Listed are consensus gene names (CGN) present in genomes from each of the 14 available phyla (12 bacterial, 2 archaeal) of 170 prokaryotes. (A) Present in all genomes from all phyla. Contrast with Table 3 (computed from 147 prokaryotes), where dnaX and rpsM are not included and where rpoB and tufA have dropped out. (B) Present in at least 90% of members from each phylum. Note that rpoB reappears in this list, but not tufA (due to a known annotation inconsistency). (C) Present in at least 80% of members from each phylum. (Note: lysS is a homonym for both class I and class II lysyl-tRNA synthetase genes ([Ibba et al. 1999], and thus represents a false positive entry.)
