Abstract
We report the use of chemical derivatization with MALDI-MS/MS analysis for de novo sequence analysis. Using three frequently used homology-based search algorithms, we were able to identify more than 40 proteins from banana, a nonmodel plant with unsequenced genome. Furthermore, this approach allowed the identification of different isoforms. We also observed that the identification score obtained varied according to the position of the peptide sequences in the query using the MS-Blast algorithm.
Methods and tools
- Banana proteome by de novo of derivatized peptides: Chemical derivatization and MALDI-TOF/TOF de novo sequencing with homology search (MS-BLAST etc.) identified more than 40 proteins and isoforms in banana, a non-model plant.
