Usage and Biology

Due to the limited number of auxotrophic markers available for Yarrowia lipolytica, we had to use antibiotic-resistance markers for the selection of possible attempted deletions in our chassis. In order to use the selection marker, we had to use 1000-2000µg/ml of mycophenolic acid (MPA) in our selection plates.

MPA tends to kill cells by inhibiting inosine monophosphate dehydrogenase (IMPDH), an important enzyme in the de novo biosynthesis of GMP. The selection marker gene, which codes for an IMPDH variant, confers resistance by bypassing this inhibition.
