Description

Net tow metaproteome of Trichodesmium species mapped to a Trichodesmium metagenome plus cyanoGEBA species genomes, analyzed by 2D LC-MS/MS in units of normalized protein spectral counts. Samples were collected in North Atlantic surface waters, at station BATS (Bermuda Atlantic Time-series Study), and station ALOHA (A Long-Term Oligotrophic Habitat Assessment) between 2000 and 2018.

Methods & Sampling

Dataset acquisition description

A 200um plankton net net was deployed to ~20m depth, then recovered to just below surface, repeating five times. Trichodesmium colonies were hand picked into 0.2um filtered surface seawater, rinsed twice in 0.2um filtered surface seawater, and decanted onto a 0.2-4um Supor filter (indicated in sample provenance table, see dataset https://www.bco-dmo.org/dataset/787093).

Proteins were extracted and trypsin digested in-gel following Saito et al., 2014 (Science). Peptides were analyzed by LC-MS/MS in data discovery mode on a Thermo Orbitrap Fusion.

Data Processing Description

Dataset Processing Description

Thermo proteome discoverer 2.2 was used to search the data with the SEQUEST algorithm. Statistical validation was performed in Scaffold (Proteome Software) at the 1% protein and peptide false discovery rate (FDR) levels.

A publicly available Trichodesium metagenome was used in this search (IMG ID 2821474806) as well as the contents of the CyanoGEBA project (Shih et al, 2013).

BCO-DMO Data Manager Processing Notes:
* Time values "00009" changed to 09:00 after checking the sample log.
* Removed column of row numbers called "Unnamed:0"
* Column names were switched kegg_pathway and pfams_id so those column names were switched to correct that. kegg_id and ncbi_name were also switched.
