Investigating Deep Phylogenetic Relationships among Cyanobacteria and Plastids by Small Subunit rRNA Sequence Analysis 1
Small subunit rRNA sequence data were generated for 27 strains of cyanobacteria and incorporated into a phylogenetic analysis of 1,377 aligned sequence positions from a diverse sampling of 53Expand
Daptomycin biosynthesis in Streptomyces roseosporus: cloning and analysis of the gene cluster and revision of peptide stereochemistry.
Daptomycin is a 13 amino acid, cyclic lipopeptide produced by a non-ribosomal peptide synthetase (NRPS) mechanism in Streptomyces roseosporus. A 128 kb region of S. roseosporus DNA was cloned andExpand
A fungal gene for antibiotic resistance on a dispensable ("B") chromosome.
A family of cytochrome P-450 (Pda) genes in the pathogenic fungus Nectria haematococca is responsible for the detoxification of the phytoalexin pisatin, an antimicrobial compound produced by gardenExpand
Molecular characterization of class 3 integrons from Delftia spp.
Two environmental strains, Delftia acidovorans C17 and Delftia tsuruhatensis A90, were found to carry class 3 integrons, which have seldom been reported and then only from pathogens in which they areExpand
Metagenomic natural product discovery in lichen provides evidence for a family of biosynthetic pathways in diverse symbioses
Significance Remarkable chemical families are being recognized by studying diverse symbioses. We identified, through metagenomics, the first cyanobacterial trans-AT polyketide biosynthetic pathway inExpand
Mitochondrial genomes from the lichenized fungi Peltigera membranacea and Peltigera malacea: features and phylogeny.
Mitochondrial genomes from the fungal partners of two terricolous foliose lichen symbioses, Peltigera membranacea and Peltigera malacea, have been determined using metagenomic approaches, includingExpand
The lipopeptide antibiotic A54145 biosynthetic gene cluster from Streptomyces fradiae
Ca2+-dependent cyclic lipodepsipeptides are an emerging class of antibiotics for the treatment of infections caused by Gram-positive pathogens. These compounds are synthesized by nonribosomal peptideExpand
Combinatorial biosynthesis of novel antibiotics related to daptomycin
Daptomycin, a cyclic lipopeptide produced by Streptomyces roseosporus, is the active ingredient of Cubicin (daptomycin-for-injection), a first-in-class antibiotic approved for treatment of skin andExpand
Natural products to drugs: daptomycin and related lipopeptide antibiotics.
Daptomycin (Cubicin) is a lipopeptide antibiotic approved in the USA in 2003 for the treatment of skin and skin structure infections caused by Gram-positive pathogens. It is a member of theExpand
The lichen symbiosis re-viewed through the genomes of Cladonia grayi and its algal partner Asterochloris glomerata
BackgroundLichens, encompassing 20,000 known species, are symbioses between specialized fungi (mycobionts), mostly ascomycetes, and unicellular green algae or cyanobacteria (photobionts). Here weExpand
