Abstract

Mevalonate is biosynthesized from acetyl-CoA and metabolized to isoprenoid compounds in a wide variety of organisms although certain types of prokaryotes employ another route for isoprenoid biosynthesis (the non-mevalonate pathway). To establish a fermentative process for mevalonate production, enzymes for mevalonate synthesis from Enterococcus faecalis were expressed in Escherichia coli, a non-mevalonate pathway bacterium. Mevalonate was accumulated, indicating a redirection of acetate metabolism by the expressed enzyme. The recombinant E. coli produced 47 g mevalonate l−1 in 50 h of fed-batch cultivation in a 2 l jar fermenter; this is the highest titer ever reported demonstrating the superiority of E. coli in its ability of acetyl-CoA supply and its inability is degrade mevalonate.
