Due to a mistake during data processing, the putative substrate-binding pocket sequences of two of the adenylation domains were switched. Consequently, the structure of the peptide (cyanopeptolin-984) produced by Microcystis NIVA-CYA 172/5 (N-C 172/5) shown in Fig. 1 is incorrect in the positioning of two amino acid residues. The underlying experimental data and the molecular mass of cyanopeptolin-984 were, however, correct. Fig. 1 showing the corrected peptide structure and corrected Tables 1 and 2 are shown in the accompanying PDF (85 kb). It should be noted that the phylogenetic tree of adenylation domain sequences (Fig. 3) is correct, but the designations for McnC1-Ile/Thr and McnE-Gln/Ile should have read McnC1-Gln/Thr and McnE-Ile, respectively. This correction makes interpretation of the phylogenetic tree more straightforward, and has no impact on the major conclusions of the paper.
