the relative biosynthesis of (8R,9Z,12Z)-8-hydroperoxy-9,12-octadecadienoate compared to (8E,10R,12Z)-10-hydroperoxy-9,12-octadecadienoate is slightly lowered
L306V
the relative biosynthesis of (8R,9Z,12Z)-8-hydroperoxy-9,12-octadecadienoate compared to (8E,10R,12Z)-10-hydroperoxy-9,12-octadecadienoate is slightly lowered
L384A
the relative amount of (8E,10R,12Z)-10-hydroperoxy-9,12-octadecadienoate (8-HODE/(10-HODE + 8-HODE)) is 10.4% for the recombinant wild-type enzyme and 53.7% for the mutant enzyme. The L384A mutant changes the stereochemistry at C-8 and C-10. L384A forms the R and S enantiomers of 8-HODE and 10-HODE in a ratio of 3:2, whereas native and recombinant 10R-DOX form both products with 95% R configuration
