Abstract
Nonribosomal peptides (NRPs) are of great pharmacological importance, but there is currently no technology for high-throughput NRP ‘dereplication’ and sequencing. We used multistage mass spectrometry followed by spectral alignment algorithms for sequencing of cyclic NRPs. We also developed an algorithm for comparative NRP dereplication that establishes similarities between newly isolated and previously identified similar but nonidentical NRPs, substantially reducing dereplication efforts.
Methods and tools
- NRP dereplication and sequencing: Sequences cyclic nonribosomal peptides from multistage mass spectrometry by spectral alignment, and dereplicates them comparatively against known NRPs. The first high-throughput route to a compound class with no genome to search and considerable pharmacological interest.
