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


ABSTRACT: 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).

Measurements of stable carbon isotope ratios (δ<sup>13</sup>C) are widely used in biology to address questions regarding food sources and metabolic pathways used by organisms. The analysis of these so-called stable isotope fingerprints (SIFs) for microbes involved in biogeochemical cycling and microbiota of plants and animals has led to major discoveries in environmental microbiology. Currently, obtaining SIFs for microbial communities is challenging as the available methods either only provide  ...[more]
