The retinoids are represented essential compounds in many biological systems. β-Carotene is cleaved by β-carotene monooxygenase to yield two molecules of retinal. β-Carotene is synthesized by using IPP (isopentenyl diphosphate) and DMAPP (dimethylallyl diphosphate) as building blocks. IPP and DMAPP can be formed in E. coli via endogenous MEP pathway and exogenous Mevalonate pathway. The rate-limiting enzyme of DXP synthase (Dxs) of MEP pathway is overexpressed and an optimized artificial Mevalonate pathway is introduced in E. coli. In order to make E. coli produce β-carotene, it is also introduced the β-carotene pathway composed of 4 foreign enzymes; GGPP synthase (CrtE), phytoene synthase (CrtB), phytoene desaturase (CrtI), and lycopene β-cyclases (CrtY). Artificial E. coli codon optimized gene was synthesized, based on the amino acid sequence of blh gene of uncultured marine bacterium 66A03. The artificial b-Carotene 15,15'-monooxygenase gene was combined with b-carotene pathway genes to make retinal plasmid, pTDHBSR. Recombinant E. coli harboring pTDHBSR produced retinol (25 mg/L), retinal (19 mg/L), and retinyl acetate (9 mg/L). This work was supported by the Basic Research Program(Grant No.2009-0084490) of MEST, the EB-NCRC (Grant No. R15-2003-012-02001-0) and BK21 program of Korea.
