RiPPs cancer Ribosomally synthesized and post-translationally modified peptides (RiPPs) represent a vast and rapidly expanding superfamily of natural productsRibosomally synthesized and post-translationally modified .... These molecules, often referred to simply as RiPPs, are characterized by their synthesis on ribosomes followed by intricate post-translational modifications (PTMs). This dual process is crucial for generating their diverse and complex structures, which in turn bestow upon them a wide array of potent biological activities. The study of RiPPs has seen significant expansion, particularly due to advancements in genome mining software and a deeper understanding of their biosynthetic pathways.

The biosynthesis of RiPPs begins with the ribosomal translation of small, gene-encoded precursor proteins. These precursor proteins serve as substrates for a streamlined series of specialized enzymes that catalyze various post-translational modifications. These modifications are not arbitrary; they are essential for the maturation and functionalization of the peptide. For instance, the biosynthesis of several classes of RiPPs involves the dehydration of serine and threonine residues, a critical step in shaping the final molecular architecture. Other common modifications include cyclization, glycosylation, and the formation of unusual amino acids.作者：T Ozaki·2023·被引用次数：23—Ribosomally synthesized and posttranslationally modified peptides(RiPPs) are growing class of natural products with potent biological ...
