This review discusses the biosynthesis of natural products that are generated by trans-AT polyketide synthases, a family of catalytically versatile enzymes that have recently been recognized as one of the major group of proteins involved in the production of bioactive polyketides. 436 references are cited.

Name: Natural product reports
Polyketides such as the clinically-valuable antibacterial agent mupirocin are constructed by architecturally-sophisticated assembly lines known as trans-acyltransferase polyketide synthases. Organelle...
The polypeptides of multimodular polyketide synthases self-assemble into biosynthetic factories. While the docking domains that mediate the assembly of cis-acyltransferase polyketide synthase polypept...
Species of the fungus Fusarium collectively cause disease on almost all crop plants and produce numerous natural products (NPs), including some of the mycotoxins of greatest concern to agriculture. Ma...
Polyketides induce prestalk cell differentiation in Dictyostelium. In the double-knockout mutant of the SteelyA and B polyketide synthases, most of the pstA cells-the major part of the prestalk cells-...
Andrimid (Adm) synthase, which belongs to the type-II system of enzymes, produces Adm in Pantoea agglomerans. The adm biosynthetic gene cluster lacks canonical acyltransferases (ATs) to load the malon...
The purpose of this study is to confirm that the two forms of the device the Integrated E-TRANS (fentanyl HCl) system and the Separated (Two-Part) E-TRANS (fentanyl HCl) System provide the...
The photorefractive keratectomy was the first correction mode refractive laser. It's a photo-ablation of a predetermined thickness of anterior corneal stroma. Debridement of epithelium can...
The objectives of this study are to : 1) determine if vaccenic acid (trans-11-octadecenoic, a naturally occurring trans fatty acid isomer from ruminant animal products) raises LDL choleste...
The purpose of this study is to evaluate the impact of Trans Sodium Crocetinate (TSC) on oxygen levels in brain tumor tissue in patients with high grade glioma. The proposed clinical indic...
The purpose of this study is to assess the effects of the combination of all-trans retinoic acid in combination with one of two schedules of Bryostatin 1 in patients with myelodysplasia an...
Large enzyme complexes composed of a number of component enzymes that are found in STREPTOMYCES which biosynthesize MACROLIDES and other polyketides.
The production of PEPTIDES or PROTEINS by the constituents of a living organism. The biosynthesis of proteins on RIBOSOMES following an RNA template is termed translation (TRANSLATION, GENETIC). There are other, non-ribosomal peptide biosynthesis (PEPTIDE BIOSYNTHESIS, NUCLEIC ACID-INDEPENDENT) mechanisms carried out by PEPTIDE SYNTHASES and PEPTIDYLTRANSFERASES. Further modifications of peptide chains yield functional peptide and protein molecules.
An anticholesteremic agent that inhibits sterol biosynthesis in animals.
Bacterial proteins that share the property of binding irreversibly to PENICILLINS and other ANTIBACTERIAL AGENTS derived from LACTAMS. The penicillin-binding proteins are primarily enzymes involved in CELL WALL biosynthesis including MURAMOYLPENTAPEPTIDE CARBOXYPEPTIDASE; PEPTIDE SYNTHASES; TRANSPEPTIDASES; and HEXOSYLTRANSFERASES.
The joining of RNA from two different genes. One type of trans-splicing is the "spliced leader" type (primarily found in protozoans such as trypanosomes and in lower invertebrates such as nematodes) which results in the addition of a capped, noncoding, spliced leader sequence to the 5' end of mRNAs. Another type of trans-splicing is the "discontinuous group II introns" type (found in plant/algal chloroplasts and plant mitochondria) which results in the joining of two independently transcribed coding sequences. Both are mechanistically similar to conventional nuclear pre-mRNA cis-splicing. Mammalian cells are also capable of trans-splicing.
