Transformation-associated recombination and heterologous expression of noncanonical depsipeptide nonribosomal peptide synthetase derived from marine Streptomyces

Jeong Sang Yi, Jin Won Choi, Ngoc Han Le Thi, Sung Jin Kim et autres

Abstract Analysis of the secondary metabolite biosynthesis gene cluster (BGC) from marine Streptomyces sp. SNJ102 revealed the presence of a noncanonical nonribosomal peptide synthetase (NRPS), predicted to produce a depsipeptide compound. The NRPS gene cluster was captured by transformation-associated recombination and heterologously …

Daldipyrenones A–C: Caged [6,6,6,6,6] Polyketides Derived from an Endolichenic Fungus Daldinia pyrenaica 047188

Seungjin Lee, In Guk Park, Jin Won Choi, Jin Young Son et autres

Daldipyrenones A–C ( 1 – 3 ), three unprecedented caged xanthone [6,6,6,6,6] polyketides featuring a spiro-azaphilone unit, were discovered from an endolichenic fungus, Daldinia pyrenaica 047188. The structures of 1 – 3 were determined by using spectroscopic analysis and chemical derivatization. Daldipyrenones …

Discovery of Bioactive Metabolites by Acidic Stress to a Geldanamycin Producer, Streptomyces samsunensis

Jin Won Choi, Yeonhee Lee, Jaekyeong Kim, Haeun Kwon et autres

In an effort to activate silent biosynthetic gene clusters, Streptomyces samsunensis DSM42010, a producer of geldanamycin, was cultured at four different pHs (4.5, 5.4, 6.6, and 7.4). An acidic culture condition (pH 5.4) was selected for a chemical investigation since S. samsunensis …

Anti-Obesity Potential through Regulation of Carbohydrate Uptake and Gene Expression in Intestinal Epithelial Cells by the Probiotic Lactiplantibacillus plantarum MGEL20154 from Fermented Food

So Young Park, Jin Won Choi, Dong Nyoung Oh, Eun Ji Lee et autres

genes in Caco-2 cells by MGEL20154 were observed. Therefore, we propose that the anti-obesity effect of the strain is exerted by inhibiting carbohydrate absorption and regulating gene expression in the intestine.
