<p>Genes idi and ispA were added to the plasmid pET-YSS, yielding pET-IAY. Co-transformation of the plasmid pET-IAY with p35151 resulted in squalene production of 69.3 mg/L (strain H2), an approximately 3.7-fold increase compared to BL21(DE3) harboring pET-YSS and p35151(Figure. 2). This result indicated that the overexpression of idi and ispA increased the supply of precursor, and thus increasing the yield of squalene.&nbsp;</p>

<p>By testing the pigmentation level，We discovered that the pigmentation level in the expression of YSS is higher than other strains expressing NSS KSS or thSQS, showing that YSS is relatively active, while the pigmentation level in strains containing pET-IAY-CN &nbsp;is 2.2 times that of strains expressing pET-YN, demonstrating that we can significantly increase the metabolic flux towards FPP by expressing idi and ispA.</p>

idi( isopentenyl-diphosphate delta-isomerase)

Isopentenyl diphosphate isomerase encodes Isopentenyl diphosphate isomerase. catalyzes the reversible isomerization of isopentenyl diphosphate (IPP) to dimethylallyl diphosphate (DMAPP), a key step in the biosynthesis of isoprenoids.
This gene is a mutant of idi from Escherichia coli JM109. idi include SpeⅠ site, so this point was muted to create Biobrick parts.
