Abstract

Cyanobactins are a rapidly growing family of linear and cyclic peptides produced by cyanobacteria. Kawaguchipeptins A and B, two macrocyclic undecapeptides reported earlier from Microcystis aeruginosa NIES-88, are shown to be products of the cyanobactin biosynthetic pathway. The 9 kb kawaguchipeptin (kgp) gene cluster was identified in a 5.26 Mb draft genome of Microcystis aeruginosa NIES-88. We verified that this gene cluster is responsible for the production of the kawaguchipeptins through heterologous expression of the kgp gene cluster in Escherichia coli. The KgpF prenyltransferase was overexpressed and was shown to prenylate C-3 of Trp residues in both linear and cyclic peptides in vitro. Our findings serve to further enhance the structural diversity of cyanobactins to include tryptophan-prenylated cyclic peptides.

Keywords: biosynthesis; cyanobactins; peptides; prenylation; prenyltransferases.

The cyclic undecapeptides Kawaguchipeptin A (1) and kawaguchipeptin B (2) reported from Microcystis aeruginosa NIES-88. Kawaguchipeptin A contains two C-3 prenylated tryptophans (highlighted).

The kawaguchipeptin biosynthetic pathway in Microcystis aeruginosa NIES-88. (A) The 10 kb biosynthetic gene cluster that consists of six biosynthetic genes (indicated by grey and black) are organized in a single operon and have homology to genes present in other known cyanobactin gene clusters. The open arrows indicate the genes that encode proteins with unknown functions. The kgpE precursor gene (black) encodes the 87 amino-acid precursor protein (B). Three identical copies of the undecapeptide core are encoded by the single precursor gene (highlighted in gray).

Heterologous expression of the kgp operon in E. coli demonstrates that the kgpA-G genes confer the production of 1 and 2 in vivo. Extracted ion chromatographs of LC–HRMS analysis of: Authentic 1 and 2 from M. aeruginosa NIES-88 (1, 2); 2 in E. coli transformed with pDK-kgp1 (3); 1 in E. coli transformed with pDK-kgp1 (4); 1 in E. coli co-transformed with pDK-kgp1 and pMBI and supplied with mevalonolactone 3 (5); and 2 in E. coli co-transformed with pDK-kgp1 and pMBI and supplied with mevalonolactone 3 (6).
