Homology-driven proteomics enables the characterization of proteomes in organisms lacking sequenced genomes. This study details practical, automated protein identification methods using LC-MS/MS and a hybrid LTQ Orbitrap mass spectrometer.
Area of Science:
- Proteomics
- Genomics
- Mass Spectrometry
Background:
- Characterizing proteomes of organisms with unsequenced genomes is challenging.
- Homology-driven proteomics offers a solution for such genomic limitations.
Purpose of the Study:
- To address practical aspects of automated homology-driven protein identification.
- To present a pipeline for LC-MS/MS data analysis on a hybrid LTQ Orbitrap mass spectrometer.
Main Methods:
- Utilized homology-driven proteomics.
- Employed Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS).
- Operated on a hybrid LTQ Orbitrap mass spectrometer.
Main Results:
- Presented a practical pipeline for automated protein identification.
- Demonstrated the utility of the approach for unsequenced genomes.
Conclusions:
- The presented pipeline facilitates automated protein identification.
- Software supporting the pipeline is publicly accessible or freely downloadable, promoting wider adoption.
