Table 1 Variation in pI in functionally classified groups of COGs. The table lists functional groups of COGs as defined in the COG website [22] along with the results of the Dunn Multiple Comparison test. Ri – mean rank for the group, Rt – mean rank for sample representing the complete distribution. Significant values are those where |Rt - Ri| > 467.35 which is calculated for α = 0.2
