Control of chitin and N-acetylglucosamine utilization in Saccharopolyspora erythraea
Ontology highlight
ABSTRACT: We report the effect of addition of N-acetylglucosamine in Saccharopolyspora erythraea reactor cultures on the transcription of genes related to dasR regulon Examination of one time-point after 45 minutes of the addition of N-acetylglucosamine in reactor cultures.

Project description:We report the high-throughput profiling of saccharopolyspora erythraea including a industrial strain HL3168 E3 and a wild-type strain NRRL23338. The aim was to evaluate the difference in expression of sRNA predicted in silico related to secondary metabolites in Saccharopolyspora erythraea.

The aim was to evaluate the difference in expression of sRNA predicted in silico related to secondary metabolites in Saccharopolyspora erythraea. Comparison of the gene expression difference in 2 Saccharopolyspora erythraea strains.
Project description:Erythromycin is a medically important antibiotic, biosynthesized by the actinomycete Saccharopolyspora erythraea. We used transcriptomic approach to compare whole genome expression in erythromycin high-producing strain, compared to the wild type S. erythraea strain in four stages of fermentation.
Project description:Saccharopolyspora erythraea NRRL2338 (wildtype) and K41-135 (overproducer strain from Kosan Biosciences, KOVP) were grown in shake flask cultures in rich medium R5. RNA samples were harvested for each strain over 5 days. 12 h samples taken for each strain were used as their respective reference ("time zero") samples. The genomic DNA control compares NRRL2338 gDNA to NRRL2338 12 h RNA to show relative gene expression at the start of the timecourse. The 12 h RNA control compares initial gene expression between the wildtype and overproducer strains. Groups of assays that are related as part of a time series. Keywords: time_series_design
