a Boxplots showing the distribution of isoelectric points of proteins according to their origins and their types. The boxplot indicates the median line, first and third quartiles. Outliers that are 1.5× above the upper quartile or below the lower quartile are indicated as dots. b Boxplots showing the distribution of the isoelectric points of components originated from bacteria. Bacterial components correspond to bacterial genes which aligned with the ChiC-gene components assigned as of bacterial origin. The boxplot indicates the median line, first and third quartiles. Outliers that are 1.5× above the upper quartile or below the lower quartile are indicated as dots
