What should we measure to get a full picture of our strain’s performance?
Product (metabolite of interest), Intermediate metabolite, Side product, On-pathway flux, Off-pathway flux
Give EX of Product (metabolite of interest).
beta-carotene
Give EX of Intermediate metabolite.
GGPP, phytoene, neurosporene, lycopene, etc
Give EX of Side product.
7,8-dihydro-beta-carotene, etc
Give EX of On-pathway flux.
Mevalonate, IPP, DMAPP, GPP, FPP, etc…
Give EX of Off-pathway flux.
Squalene, monoterpenes, ergosterol, etc…
How can we detect and measure multiple metabolites within the same sample?
LCMS
How does LCMS data work?
correlates intensity with concentration (MS)
