Ribosomally synthesized and post-translationally modified peptide natural products: overview and recommendations for a universal nomenclature.
This review presents recommended nomenclature for the biosynthesis of ribosomally synthesized and post-translationally modified peptides (RiPPs), a rapidly growing class of natural products. The
Patellamide A and C biosynthesis by a microcin-like pathway in Prochloron didemni, the cyanobacterial symbiont of Lissoclinum patella.
TLDR
The full sequencing and functional expression of a marine natural-product pathway from an obligate symbiont is presented, and a related cluster was identified in Trichodesmium erythraeum IMS101, an important bloom-forming cyanobacterium.
A global assembly line for cyanobactins.
TLDR
By comparing five new cyanobactin biosynthetic clusters, an assembly line responsible for the biosynthesis of these diverse peptides is reported, which produced the prenylated antitumor preclinical candidate trunkamide in Escherichia coli culture using genetic engineering.
Natural combinatorial peptide libraries in cyanobacterial symbionts of marine ascidians
A large family of cytotoxic cyclic peptides exemplified by the patellamides has been isolated from ascidians harboring the obligate cyanobacterial symbionts Prochloron spp.1,2,3,4,5. Genome sequence
Genome streamlining and chemical defense in a coral reef symbiosis
TLDR
It is shown that the large patellazoles biosynthetic pathway is maintained, whereas the remainder of the genome is undergoing extensive streamlining to eliminate unneeded genes.
The Complete Genome of Teredinibacter turnerae T7901: An Intracellular Endosymbiont of Marine Wood-Boring Bivalves (Shipworms)
TLDR
The results suggest that T. turnerae is likely a facultative intracellular ensosymbiont whose niche presently includes, or recently included, free-living existence.
Identification of the antifungal peptide-containing symbiont of the marine sponge Theonella swinhoei as a novel δ-proteobacterium, “Candidatus Entotheonella palauensis”
TLDR
The 16S rRNA gene sequence was determined using a combination of denaturing gradient-gel electrophoresis (DGGE) and specific polymerase chain-reaction (PCR) primers, and its source was confirmed by in situ hybridization.
Complex microbiome underlying secondary and primary metabolism in the tunicate-Prochloron symbiosis
TLDR
This study unveils the complex L. patella microbiome and its impact on primary and secondary metabolism, revealing a remarkable versatility in creating and exchanging small molecules.
Ribosomal peptide natural products: bridging the ribosomal and nonribosomal worlds.
TLDR
The major structural and biosynthetic categories of ribosomally synthesized bacterial natural products and, where applicable, compare them to their homologs from nonribosomal biosynthesis are summarized.
Equisetin biosynthesis in Fusarium heterosporum.
An iterative polyketide synthase-peptide synthetase hybrid assembles the HIV-1 integrase inhibitory tetramic acid, equisetin, in the filamentous fungus Fusarium heterosporum.
