Assessing the Impact of the Leader Peptide in Protease Inhibition by the Microviridin Family of RiPPs.

Ribosomally synthesized and post-translationally modified peptides (RiPPs) are a growing class of natural products biosynthesized from a genetically encoded precursor peptide. RiPPs have attracted attention for the ability to generate and screen libraries of these compounds for useful biological activities. To facilitate this screening, it is useful to be able to do so with the leader peptide still present.
