How a Subfamily of Radical S-Adenosylmethionine Enzymes Became a Mainstay of Ribosomally Synthesized and Post-translationally Modified Peptide Discovery

[Image: see text] Radical S-adenosylmethionine (rSAM) enzymes are a large and diverse superfamily of enzymes, some of which are known to participate in the biosynthesis of ribosomally synthesized and post-translationally modified peptides (RiPPs). Specifically, a subfamily of rSAM proteins with an e...

description [Image: see text] Radical S-adenosylmethionine (rSAM) enzymes are a large and diverse superfamily of enzymes, some of which are known to participate in the biosynthesis of ribosomally synthesized and post-translationally modified peptides (RiPPs). Specifically, a subfamily of rSAM proteins with an elongated C-terminus known as a SPASM domain have become a fixation in the discovery of new RiPP natural products. Arguably, a structural study, a bioinformatic study, and a functional study built the foundation of the research for rSAM-SPASM-protein-modified RiPPs. In this Review, we focus on these three studies and how they initiated what has become an increasingly productive field. In addition, we discuss the current state of RiPPs that depends on rSAM-SPASM proteins and provide guidelines to consider in future research. Lastly, we discuss how genome mining tools have become a powerful means to identify and predict new RiPP natural products. Despite the state of our current knowledge, we do not completely understand the relationship of rSAM-SPASM chemistry, substrate recognition, and the structure–function relationship as it pertains to RiPP biosynthesis, and as such, there remain many interesting findings waiting to be discovered in the future.
