Web17 de mai. de 2009 · PedH seems to be involved in the biosynthesis of an onnamide-like terminus with an analogous saturated moiety that is oxidatively cleaved off and therefore not present in the final structure 11,26. WebThis symbiont hypothesis, however, remained unproven because of a general inability to cultivate the suspected producers. However, we have recently identified an uncultured Pseudomonas sp. symbiont as the most likely producer of the defensive antitumor polyketide pederin in Paederus fuscipes beetles by cloning the putative biosynthesis …
Genomic studies suggest strong homology with Ped genes, which encode the production of pederins, structurally similar compounds synthesized by bacterial endosymbionts of Paederus beetles. This suggests that onnamide A is actually the product of bacterial endosymbionts of the marine sponges from which the compound was first isolated. Thus, the biosynthetic pathway of onnamide A i… Web11 de nov. de 2004 · Comparison of the onn gene cluster with the ped system and proposed onnamide A biosynthesis.
