Complete genome sequence of Catenulispora acidiphila type strain (ID 139908).

Project description:Catenulispora acidiphila Busti et al. 2006 is the type species of the genus Catenulispora, and is of interest because of the rather isolated phylogenetic location it occupies within the scarcely explored suborder Catenulisporineae of the order Actinomycetales. C. acidiphilia is known for its acidophilic, aerobic lifestyle, but can also grow scantly under anaerobic conditions. Under regular conditions, C. acidiphilia grows in long filaments of relatively short aerial hyphae with marked septation. It is a free living, non motile, Gram-positive bacterium isolated from a forest soil sample taken from a wooded area in Gerenzano, Italy. Here we describe the features of this organism, together with the complete genome sequence and annotation. This is the first complete genome sequence of the actinobacterial family Catenulisporaceae, and the 10,467,782 bp long single replicon genome with its 9056 protein-coding and 69 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.

Diterpene Biosynthesis in Catenulispora acidiphila: On the Mechanism of Catenul-14-en-6-ol Synthase.

Project description:A new diterpene synthase from the actinomycete Catenulispora acidiphila was identified and the structures of its products were elucidated, including the absolute configurations by an enantioselective deuteration approach. The mechanism of the cationic terpene cyclisation cascade was deeply studied through the use of isotopically labelled substrates and of substrate analogues with partially blocked reactivity, resulting in derailment products that gave further insights into the intermediates along the cascade. Their chemistry was studied, leading to the biomimetic synthesis of a diterpenoid analogue of a brominated sesquiterpene known from the red seaweed Laurencia microcladia.

Structural characterization of a hypothetical protein: a potential agent involved in trimethylamine metabolism in Catenulispora acidiphila.

Project description:Catenulispora acidiphila is a newly identified lineage of actinomycetes that produces antimicrobial activities and represents a promising source of novel antibiotics and secondary metabolites. Among the discovered protein coding genes, 68 % were assigned a putative function, while the remaining 32 % are genes encoding "hypothetical" proteins. Caci_0382 is one of the "hypothetical" proteins that has very few homologs. Sequence analysis shows that the protein belongs to the NTF2-like protein family. The structure of Caci_0382 demonstrates that it shares the same fold and has a similar active site as limonene-1,2-epoxide hydrolase, which suggests that it may have a related function. Using a fluorescence thermal shift assay, we identified stabilizing compounds that suggest potential natural ligands of Caci_0382. Using this information, we determined the crystal structure in complex with trimethylamine to provide a better understanding of the function of this uncharacterized protein.

Lsr2 and its novel paralogue mediate the adjustment of Mycobacterium smegmatis to unfavorable environmental conditions

Project description:In this study, we analyze the role of Lsr2 as a transcription factor in M. smegmatis, a saprophytic bacterium whose natural habitat (soil and water) substantially differs from that of the obligatory mycobacterial pathogens. In summary, the combined RNA-seq and ChIP-seq data revealed that Lsr2 controls gene expression either directly by binding their promoter regions or indirectly through DNA loop formation.

Heavy metal resistance in Cupriavidus metallidurans CH34 is governed by an intricate transcriptional network

Project description:Background: The high number of heavy metal resistance genes in the soil bacterium Cupriavidus metallidurans CH34 makes it an interesting model organism to study microbial responses to heavy metals. Results: In this study the transcriptional response of this bacterium was measured after challenging it to a wide range of sub-lethal concentrations of various essential or toxic metals. Considering the global transcriptional responses for each challenge as well as by identifying the overlap in upregulated genes between different metal responses, the sixteen metals could be clustered in three different groups. Additionally, next to the assessment of the transcriptional response of already known metal resistance genes, new metal response gene clusters were identified. The majority of the metal response loci showed similar expression profiles when cells were exposed to different metals, suggesting complex cross-talk at transcriptional level between the different metal responses. The highly redundant nature of these metal resistant regions – illustrated by the large number of paralogous genes – combined with the phylogenetic distribution of these metal response regions within evolutionary related and other metal resistant bacteria, provides important insights on the recent evolution of this naturally soil dwelling bacterium towards a highly metal-resistant strain found in harsh and anthropogenic environments. Conclusions: The metal-resistant soil bacterium Cupriavidus metallidurans CH34 displays myriads of gene expression patterns when exposed to a wide range of heavy metals at non-lethal concentrations. The interplay between the different gene expression clusters points towards a complex cross-regulated regulatory network governing heavy metal resistance in C. metallidurans CH34. Keywords: Cupriavidus metallidurans CH34, transcriptional regulation, heavy metal resistance

Proteomics of Nitrospirae - Rice paddy Nitrospirae encode and express genes related to sulfate respiration: proposal of the new genus Candidatus Sulfobium

Project description:We present the draft genome of Nitrospirae bacterium Nbg-4 as a representative of this clade and couple this to in situ protein expression under sulfate-enriched and sulfate-depleted conditions in rice paddy soil. The proteins were extracted from the soil and analysed via LC-MS/MS measurements.
