Proteomes of twenty bacterial, archaeal and eukaryotic species for bench marking of Direct Protein-SIF (stable carbon isotope fingerprinting proteomics)

Project description:We developed a method that allows measuring the stable carbon isotope composition of individual species in microbial communities using metaproteomics. We call this methods “Direct Protein-SIF”. To benchmark this method, we measured twenty pure culture species using the Direct Protein-SIF method as well as Isotope Ratio Mass Spectrometry. Some of the pure cultures were measured in technical replicates to see how consistent Protein-SIF measurements are between mass spec runs. This submission thus contains 29 raw files for the pure cultures. See table in the submission for details of which species was measured for which .raw file. We also included the Direct Protein-SIF specific isotope pattern files as well as the .mzML files and PSM files required as input for the Direct Protein-SIF software. In addition to the pure culture a protein reference material (MKH files) was measured. The respective .raw files and isotopic pattern files are also included in this submission (see publication for details on how the reference material is used to calibrate the method).

Metaproteomics of the marine gutless oligochaete Olavius algarvensis and its symbionts to determine stable isotope fingerprints using Direct Protein-SIF

Project description:We developed a method that allows measuring the stable carbon isotope composition of individual species in microbial communities using metaproteomics. We call this methods “Direct Protein-SIF”. We validated and tested the method extensively using pure cultures (PXD006762) and mock communities (PXD006118, https://www.ebi.ac.uk/pride/archive/projects/PXD006118). As a case study we applied Direct Protein-SIF to the Olavius algarvensis symbiosis. Olavius algarvensis is a marine worm that lives in shallow-water sediments off the coast of Elba, Italy. The worm has no digestive and excretory system, instead it harbors five bacterial symbionts that fulfill its nutritional and waste recycling needs (http://www.pnas.org/content/109/19/E1173.short). For this project we generated metaproteomes of 14 O. algarvensis individuals. A total of 18 LC-MS/MS runs were generated. For Direct Protein-SIF the data from all runs was combined. In this submission we are including the Direct Protein-SIF specific isotope pattern file as well as the .mzML files and PSM file required as input for the Direct Protein-SIF software (Calis-p). In addition to the Olavius algarvensis samples a protein reference material (MKH files) was measured. The respective .raw files and isotopic pattern files are available through project PXD006762 (see publication for details on how the reference material is used to calibrate the method).

Proteomics of Ca. Riegeria standrea – the chemosynthetic symbionts of the marine flatworm Paracatenula from the Bay of Sant´Andrea (Elba, Italy)

Project description:Paracatenula are marine catenulid flatworms occuring in shallow water sediments. Adult Paracatenula lack a mouth and a digestive system. Instead, a trophosome containing intracellular alphaproteobacterial symbionts, namely Ca. Riegeria fill most of the worm´s body (Gruber-Vodicka et al., 2011). Paracatenula sp. ‘standrea’ that harbor Ca. Riegeria sp. 812A (standrea) were sampled in Elba, Italy in April 2016. Based on the genome of Ca. Riegeria sp. 812A (standrea) we discovered a versatile combination of storage and biosynthesis and a convergence with unrelated intracellular thiotrophic symbionts. Proteomic analyses were performed to investigate which symbiont genes related to the host nutrition were expressed.

Labeling Escherichia coli to saturation with 2.5 % of 15N ammonium in two conditions (aerobic and anaerobic) for benchmarking of protein-based stable isotope probing proteomics (Protein-SIP)

Project description:This dataset is part of a study aimed at developing algorithms for the quantification of stable isotope content in microorganisms after labeling them with stable isotope-labeled substrates. For this dataset Escherichia coli cultures were labeled with 2.5 % of 15N-labeled NH4Cl and grown either anaerobically or aerobically. Cultures of E. coli were grown in M9 minimal medium in which 2.5 % of the ammonium was replaced with 15N-labeled NH4Cl for >10 generations to achieve close to complete labeling of cells. Triplicate cultures were grown. Please note that the unlabeled ammonium that was used of course had a natural content of 15N of around 0.4 %, thus the 0% added label samples have an actual 15N content of 0.4 % and all added label is on top of this value. We included a tab delimited table with this submission providing details on all raw files.

An omics-based metabolic model of methane-driven denitrification by aerobic methanotrophic bacteria

Project description:Methylomonas denitrificans is the first characterized organism that couples methane oxidation to nitrate reduction in pure culture without a partner. The aim of this study is to develop a metabolic model of methane driven nitrate respiration using a multi-level omics approach. Samples of M. denitrificans biomass were harvested during growth at high and limiting oxygen and whole transcriptome/proteome analyses were carried out on samples from both conditions. Comparative analysis of transcript and protein abundance between the two conditions was used to develop a metabolic model of methane driven nitrate respiration. 1.

Quantification of mock microbial communities with metagenomes, 16S rRNA gene amplicons and metaproteomics

Project description:In this study we developed metaproteomics based methods for quantifying taxonomic composition of microbiomes (microbial communities). We also compared metaproteomics based quantification to other quantification methods, namely metagenomics and 16S rRNA gene amplicon sequencing. The metagenomic and 16S rRNA data can be found in the European Nucleotide Archive (Study number: PRJEB19901). For the method development and comparison of the methods we analyzed three types of mock communities with all three methods. The communities contain between 28 to 32 species and strains of bacteria, archaea, eukaryotes and bacteriophage. For each community type 4 biological replicate communities were generated. All four replicates were analyzed by 16S rRNA sequencing and metaproteomics. Three replicates of each community type were analyzed with metagenomics. The "C" type communities have same cell/phage particle number for all community members (C1 to C4). The "P" type communities have the same protein content for all community members (P1 to P4). The "U" (UNEVEN) type communities cover a large range of protein amounts and cell numbers (U1 to U4). We also generated proteomic data for four pure cultures to test the specificity of the protein inference method. This data is also included in this submission.

Mock microbial community with spike-ins of 13C-labeled Escherichia coli cells for benchmarking of protein-based stable isotope probing proteomics (Protein-SIP)

Project description:This dataset is part of a study aimed at developing algorithms for the quantification of stable isotope content in microorganisms in microbial communities after labeling them with stable isotope-labeled substrates. For this dataset Escherichia coli cultures were labeled with different percentages (1, 5 and 10%) of fully labeled 13C glucose (13C1-6) and spiked-in into a mock microbial community consisting of 32 species of bacteria, archaea, eukaryote and bacteriophages (UNEVEN Community described in Kleiner et al. 2017 Nat Communications 8(1):1558). The community also contained unlabeled E. coli cells and labeled/unlabeled E. coli cells in the spike-in sample were at a 1:1 ratio. Cultures of E. coli were grown in M9 minimal medium in which a percentage of the glucose was replaced with 13C1-6 glucose for >10 generations to achieve close to complete labeling of cells. The following percentages of 13C1-6 glucose were added 1, 5 and 10%. Triplicate cultures were grown for each percentage. Please note that the unlabeled glucose that was used of course had a natural content of 13C of around 1.1%, thus the 0% added label samples have an actual 13C content of 1.1% and all added label is on top of this value. We included a tab delimited table with this submission providing details on all raw files.
