Clustering the three-dimensional structures of pectin lyases. The pectin lyase dataset was clustered by the un-weighted pair group method using the arithmetic mean (UPGMA) [53] with a similarity matrix obtained by the Voronoi contact method [51] using the ProCKSI-Server [52]. The tree image was generated using Dendroscope software [77]. A. Three-dimensional structure of PEL B from A. niger [PDB:1QCX]. B-C. Three-dimensional structures of the PNLs from C. lindemuthianum [GenBank: JN034039] and P. carotovorum [GenBank: AAA24856] respectively, predicted by homology modeling using the Swiss-Model Server [48].
