1. A membrane-bound prenyltransferase catalyzes the O-prenylation of 1,6-dihydroxyphenazine in the marine bacterium Streptomyces sp. CNQ-509
Philipp Zeyhle, Judith S Bauer, Marco Steimle, Franziska Leipoldt, Manuela Rösch, Jörn Kalinowski, Harald Gross, Lutz Heide Chembiochem. 2014 Nov 3;15(16):2385-92. doi: 10.1002/cbic.201402394. Epub 2014 Sep 15.
Streptomyces sp. CNQ-509 produces the rare O-prenylated phenazines marinophenazines A and B. To identify the enzyme catalyzing the O-prenyl transfer in marinophenazine biosynthesis, we sequenced the genome of S. sp. CNQ-509. This led to the identification of two genomic loci harboring putative phenazine biosynthesis genes. The first locus contains orthologues for all seven genes involved in phenazine-1-carboxylic acid biosynthesis in pseudomonads. The second locus contains two known phenazine biosynthesis genes and a putative prenyltransferase gene termed cnqPT1. cnqPT1 codes for a membrane protein with sequence similarity to the prenyltransferase UbiA of ubiquinone biosynthesis. The enzyme CnqPT1 was identified as a 1,6-dihydroxyphenazine geranyltransferase, which catalyzes the C-O bond formation between C-1 of the geranyl moiety and O-6 of the phenazine scaffold. CnqPT1 is the first example of a prenyltransferase catalyzing O-prenyl transfer to a phenazine.
2. Nonomuraea sp. ATCC 55076 harbours the largest actinomycete chromosome to date and the kistamicin biosynthetic gene cluster

Glycopeptide antibiotics (GPAs) have served as potent clinical drugs and as an inspiration to chemists in various disciplines. Among known GPAs, complestatin, chloropeptin, and kistamicin are unique in that they contain an unusual indole-phenol crosslink. The mechanism of formation of this linkage is unknown, and to date, the biosynthetic gene cluster of only one GPA with an indole-phenol crosslink, that of complestatin, has been identified. Here, we report the genome sequence of the kistamicin producer Nonomuraea sp. ATCC 55076. We find that this strain harbours the largest actinobacterial chromosome to date, consisting of a single linear chromosome of ~13.1 Mbp. AntiSMASH analysis shows that ~32 biosynthetic gene clusters and ~10% of the genome are devoted to production of secondary metabolites, which include 1,6-dihydroxyphenazine and nomuricin, a new anthraquinone-type pentacyclic compound that we report herein. The kistamicin gene cluster (kis) was identified bioinformatically. A unique feature of kis is that it contains two cytochrome P450 enzymes, which likely catalyze three crosslinking reactions. These findings set the stage for examining the biosynthesis of kistamicin and its unusual indole-phenol crosslink in the future.

Antimicrobial multidrug resistance (MDR) is a global challenge, not only for public health, but also for sustainable agriculture. Antibiotics used in humans should be ruled out for use in veterinary or agricultural settings. Applying antimicrobial peptide (AMP) molecules, produced by soil-born organisms for protecting (soil-born) plants, seems a preferable alternative. The natural role of peptide-antimicrobials, produced by the prokaryotic partner of entomopathogenic-nematode/bacterium (EPN/EPB) symbiotic associations, is to sustain monoxenic conditions for the EPB in the gut of the semi-anabiotic infective dauer juvenile (IJ) EPN. They keep pathobiome conditions balanced for the EPN/EPB complex in polyxenic (soil, vanquished insect cadaver) niches. Xenorhabdus szentirmaii DSM16338(T) (EMC), and X. budapestensis DSM16342(T) (EMA), are the respective natural symbionts of EPN species Steinernema rarum and S. bicornutum. We identified and characterized both of these 15 years ago. The functional annotation of the draft genome of EMC revealed 71 genes encoding non-ribosomal peptide synthases, and polyketide synthases. The large spatial Xenorhabdus AMP (fabclavine), was discovered in EMA, and its biosynthetic pathway in EMC. The AMPs produced by EMA and EMC are promising candidates for controlling MDR prokaryotic and eukaryotic pathogens (bacteria, oomycetes, fungi, protozoa). EMC releases large quantity of iodinin (1,6-dihydroxyphenazine 5,10-dioxide) in a water-soluble form into the media, where it condenses to form spectacular water-insoluble, macroscopic crystals. This review evaluates the scientific impact of international research on EMA and EMC.
