β-carotene synthesis
β-carotene is produced from the products of glycolysis, as can be seen in the overview figure. We have concentrated on two areas of β-carotene for our project. The first involves transfering genes from Pantoea ananatis, a member of the proteobacteria naturally capable of synthesising β-carotene. The second involves upregulating the glycolysis pathways in E. coli in order to concentrate more energy into making β-carotene.
Directly involved genes from P. ananatis
- Geranyl diphosphate synthase (crtE) converts the substrates farnesyl diphosphate and isopentyl diphosphate into geranyl geranyl diphosphate.
- Geranyl geranyl diphosphate is then converted into phytoene by phytoene synthase (crtB).
- Lycopene is produced from phytoene by phytoene desaturase (crtI).
- Finally, lycopene β-cyclase (crtY) cyclises lycopene to produce β-carotene.
Indirectly involved genes from E. coli
Overview
- In blue are the genes which we manipulated.
