Figure 2From: Linear array of conserved sequence motifs to discriminate protein subfamilies: study on pyridine nucleotide-disulfide reductasesTree of the sequence relationship among 44 selected PNDR members. Class I, class II, and the proposed class III and class IV segregate in 4 different central branches. The tree was obtained using neighbor-joining analysis of a subset of 44 random selected proteins sequences, using the distance matrix of the MSA built with ClustalX. The tree was visualized by TreeView software.Back to article page
