On the base of the constructing phylogenetic tree using PAUP 4.0, MP and NJ (neighbor-joining) trees of diverse pectate and pectin lyases showed that pectate lyases from plant, pectin lyases from fungi and pectate lyases from bateria belong to different groups, respectively. The pectate lyase A of Aspergillus nidulans is more closely related to plant pectate lyases than to pectin lyase from fungi and pectate lyases from bacteria. The pectin lyase from Pseudomonas syringae is more closely related to fungi pectin lyases than other lyases.
