proposed mechanism of DsFAD2-2: removal of a C-11 hydrogen atom from trans-DELTA12-linoleic acid by the diiron-oxo center of DsFAD2-2 results in the shift of the cis-DELTA9 double bond to the trans-DELTA10 position. The radical remaining at the C-9 position is then able to remove an oxygen atom from the diiron-oxo center because of close proximity to the catalytic core of DsFAD2-2 as dictated by the substrate binding properties of this enzyme |
