The gene transfer agent-like particle of the marine phototrophic bacterium Rhodovulum sulfidophilum
Gene transfer agents (GTAs) are shaped like bacteriophage particles but have many properties that distinguish them from bacteriophages. GTAs play a role in horizontal gene transfer in nature and thus affect the evolution of prokaryotic genomes. In the course of studies on the extracellular production of designed RNAs using the marine bacterium Rhodovulum sulfidophilum, we found that this bacter...
متن کاملExtracellular tRNAs of the marine photosynthetic bacterium Rhodovulum sulfidophilum are not aminoacylated.
The marine photosynthetic bacterium Rhodovulum sulfidophilum produces nucleic acids extracellularly. We have identified these extracellular RNAs as fully mature sized tRNAs and fragments of 16S and 23S rRNAs. Most of the tRNAs have mature 3'-terminal CCA sequences. In the present study we found that these extracellular tRNAs were not aminoacylated, although almost all intracellular tRNAs are am...
متن کاملAliphatic long-chain C20 polyesters from olefin metathesis.
Self-metathesis of undecenoic acid with [(PCy3)2Cl2Ru=CHPh] (2), followed by exhaustive hydrogenation yielded pure 1,20-eicosanedioic acid (5) (>99%) free of side-products from isomerization. Polycondensation with eicosane-1,20-diol (6), formed by reduction of the diol, yielded polyester 20,20 (Tm = 108 °C). By comparison, the known ADMET polymerization of undec-10-enyl undec-10-enoate (7), and...
متن کاملNovel macrolactins as antibiotic lactones from a marine bacterium.
Seven new macrolactins (named G~M) and known macrolactins A and F were isolated from a culture broth of Bacillus sp. PP19-H3. The strain had been isolated from the macroalga, Schizymenia dubyi. Macrolactin A, which was 24-membered lactone, had previously been reported to show antibacterial, cytotoxic and antiviral activities. The new macrolactins include 22-membered ring or dicyclic lactone in ...
متن کاملDraft Genome Sequences of Three Closely Related Isolates of the Purple Nonsulfur Bacterium Rhodovulum sulfidophilum
We report here the draft genome sequences of three isolates of Rhodovulum sulfidophilum from a single population that will serve as a model system for understanding genomic traits that underlie metabolic variation within closely related marine purple nonsulfur bacteria in natural microbial communities.
