The true complexity and diversity of ribosomally synthesized and post-translationally modified peptides (RiPPs) emerge during the post-translational modification (PTM) phase. This is where the initial precursor peptides undergo a remarkable transformation, guided by specialized enzyme systems. These modifications can include a wide array of biochemical reactions, such as cyclization, glycosylation, phosphorylation, and the incorporation of non-canonical amino acids or other chemical moieties. A significant class of enzymes involved in these modifications are radical SAM enzymes, which play critical roles in the biosynthesis of many RiPPs. Furthermore, P450 enzymes are also implicated, leading to the discovery of 11 novel P450-modified RiPPs with distinct cross-linking patterns, highlighting the chemical diversity achievable.
