||P.7 right column 3rd paragraph: "However, despite these efforts, CoQ10 levels in E. coli (0.45–3.63 mg/g DCW) still fall short of the levels produced by native producers (R. sphaeroides and A. tumefaciens) [primary source 99] (Table 2)." P.8 left column 2nd paragraph: "Unfortunately, similar to E. coli, S. cerevisiae natively produces CoQ6 not CoQ10 [ref 1]. Early attempts to delete the COQ1 gene in S. cerevisiae and replace it with DPS [decaprenyl
diphosphate synthase] from G. suboxydans under the COQ1 promoter reportedly yielded 12.3 µg/g DCW [primary source 85]. However, DPS tends to require a heterodimer formation for proper function and, when expressed, may instead form dimers with native polyprenyl diphosphate synthases to produce products of differing lengths [ref 125] (Table 2)."
