Beschreibungen/Notizen

• J1074 is recognized as an effective host for heterologous production of natural products. Its fast growth and efficient genetic toolbox due to a naturally minimized genome have contributed towards its advantage in expressing biosynthetic pathways for a diverse repertoire of products such as antibiotics and flavonoids. In order to develop precise model-driven engineering strategies for de novo production of natural products, a genome-scale metabolic model (GEM) was reconstructed for the microorganism based on protein homology to model species while drawing annotated data from databases and literature for further curation. To demonstrate its capabilities, the -GEM was used to predict overexpression targets for desirable compounds using flux scanning with enforced objective function (FSEOF). -GEM was also utilized to investigate the effect of a minimized genome on metabolic gene essentialities in comparison to another species, .
