LovG: the thioesterase required for dihydromonacolin L release and lovastatin nonaketide synthase turnover in lovastatin biosynthesis

The cryptic thioesterase LovG is found to be responsible for product release from the lovastatin nonaketide synthase (LNKS or LovB). The same enzyme also helps improving turnover of LovB through hydrolysis of incorrectly tailored intermediates.
