Metaproteomic Profiles of Healthy and Diseased Brazilian Coral

A 2020 metaproteomic study identified 361 different proteins from 6,363 MS/MS spectra in the stony coral Mussismilia braziliensis. The data compares protein expression between healthy corals and those affected by White Plague Syndrome and Black Band Disease. It was produced by Gizele D. Garcia to understand metabolic shifts during coral disease.

Use Cases

• Identify protein markers like tubulin, histone, and Rab family proteins as indicators of holobiont homeostasis in healthy corals.
• Analyze the shift from aerobic nitrogen-fixing bacterial proteins to facultative/anaerobic sulphate-reducing bacterial proteins in White Plague Syndrome-affected corals.
• Study the predominance of cyanobacterial proteins such as Hsp60, Hsp90, and adenosylhomocysteinase in Black Band Disease corals to assess oxidative stress.
• Compare chaperone protein expression (e.g., hsp70, hsp90, calreticulin) related to Cnidaria-Symbiodinium endosymbiosis across health states.

Strengths

• Contains 6,363 identified MS/MS spectra providing a substantial proteomic signal.
• Defines 361 distinct proteins, offering a detailed molecular profile.
• Explicitly compares three critical biological states: healthy, WPS-affected, and BBD-affected corals.
• Data is associated with a specific coral species (Mussismilia braziliensis) and location (Abrolhos reef system).

Limitations

• The underlying raw spectral or quantitative data tables are not provided, limiting direct computational re-analysis.
• Sample size and biological replication details for each health condition are not specified.
• The dataset is a static snapshot from a 2020 publication and may not reflect current coral health conditions.
