Metabolic engineering for efficient supply of acetyl-CoA from different carbon sources in Escherichia coli

Abstract

Metabolically engineered E. coli strains were developed for NAG production. The metabolic pathways of acetyl-CoA from glucose, acetate, or fatty acid were optimized for efficient acetyl-CoA supply to enhance NAG production. The metabolic strategies for efficient acetyl-CoA supply used in this study can be exploited for other chemicals that use acetyl-CoA as a precursor or when acetylation is involved.
