🚨 New paper out in the Journal of Natural Products!
In collaboration with the University of Granada through the Micro-Lichens project, we report the discovery of new glycinocins (E-H) lipopeptides with calcium-dependent antibiotic activity.
Interestingly, standard Marfey’s analysis couldn’t resolve the absolute configuration of all amino acids. By combining biosynthetic gene cluster (BGC) analysis with Marfey’s at lower temperature, we successfully determined their stereochemistry.

In an antifungal screening of extracts from microbial strains isolated from gypsum outcrops in Granada, Spain, four new cyclic lipopeptides, glycinocins E–H (1–4), were identified from Streptomyces sp. CA-297274 and exhibited potent activity against Zymoseptoria tritici, the causal agent of sept...
