The comparison focuses on the two clades of the protist-type lysozymes (p-lys) and one clade of the invertebrate-type lysozymes (i-lys), using ANOVA and the Tukey-Kramer posthoc tests performed with the program JMP IN 5.1.2. Significant pairwise posthoc comparisons are indicated by the respective clade numbers. Protein length, molecular weight (MW, to be multiplied by 1000), isoelectric point (pI), charge, and grand average hydropathy are given with the standard error of the mean.
