General scheme for RiPP biosynthesis. All RiPPs are synthesized first at the ribosome as a precursor peptide. This peptide consists of a core peptide segment which is typically preceded (and occasionally followed) by a leader peptide segment and is typically ~20-110 residues long.
The mycofactocin biosynthesis pathway is one of the most abundant of any RiPP system in the collection of bacterial genomes sequenced to date. However, its species distribution is heavily skewed towards the Actinomycetota , including Mycobacterium tuberculosis , which is the causative agent of tuberculosis and therefore the number one killer ...
Darobactin is a RiPP, that is, a ribosomally synthesized and post-translationally modified peptide. Its production and export is encoded by a typically silent five gene operon that showed minimal production under laboratory culture conditions.

Recent genome mining has shown that the biosynthetic gene cluster responsible for microviridin biosynthesis is much more prevalent, found in many species of Pseudomonadota (formerly Proteobacteria) and Bacteriodota (formerly Bacteriodetes). [1] Microviridins are members of the RiPP family of natural products.

Patellamide A originates from a ribosomal peptide, making it a member of the RiPP superfamily of natural products. This was determined after genome sequencing of P. didemi showed a lack of non ribosomal peptide synthetases. [2] The biosynthetic gene cluster for patellamide A contains the genes patA, patB, patC, patD, patE, patF and patG. [2]
Protein biosynthesis (or protein synthesis) is a core biological process, occurring inside cells, balancing the loss of cellular proteins (via degradation or export) through the production of new proteins. Proteins perform a number of critical functions as enzymes, structural proteins or hormones.
