This is our interview with Nadine Ziermert, from the University of Tubingen. This continues our short series of genome mining, the science of examining DNA sequence to try and predict the structures of secondary metabolites and to understand their evolution. It was a fun, wide-ranging conversation, where we talked about our shared experience working with the marine bacteria Salinispora at Scripps Institution of Oceanography, her accidental entry into data analysis, the evolution of secondary metabolite pathways as viewed through metagenome studies, and what more JGI and others can do to enable progress in this area of natural products.
