From: Convergent evolution of [D-Leucine1] microcystin-LR in taxonomically disparate cyanobacteria
Conservative evolutionary history of domains surrounding the McyA 2 adenylation domain in the microcystin biosynthetic gene cluster. Maximum-likelihood tree based on amino acid sequences of the (a) condensation domain, (b) peptidyl carrier protein domain and (c) epimerization domain within the mcy gene cluster. Phylogenetic tree inferred using MEGA 5. Bootstrap values above 50 per cent from 1000 respectively neighbor-joining, maximum parsimony and maximum-likelihood bootstrap replicates are given at the nodes. The studied strains are in bold and indicated with *.
