FASTA file of sequences in Trichodesmium field metaproteomes mapped to a Trichodesmium metagenome plus cyanoGEBA species genomes from samples collected in the Atlantic and Pacific Ocean between 2000 and 2018

Abstract:

FASTA file of sequences in Trichodesmium field metaproteomes analyzed by 2D LC-MS/MS mapped to a Trichodesmium metagenome (IMG ID 2821474806) plus cyanoGEBA species genomes (Shih et al, 2013). 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

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

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.t

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). This fasta file contains the sequences that were identified in the metaproteome analysis.
