enzyme schematic (IMAGE) DOE/Brookhaven National Laboratory Caption A plant enzyme called ACCase acts like a four-gear "machine" to crank out fatty acids, the building blocks of oil. High levels of ordinary fatty acids, or even small amounts of specialty hydroxy fatty acids, trigger a substitution in the machinery: BADC, which acts like a gear with no teeth, takes the place of BCCP, slowing production down. Plants bred to lack genes for making BADC could potentially produce large amounts of economically important fatty acids.
