L306A
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
Aspergillus fumigatus
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
Aspergillus fumigatus
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
Aspergillus fumigatus
L384F
increases the relative biosynthesis of (8R,9Z,12Z)-8-hydroperoxy-9,12-octadecadienoate compared to (8E,10R,12Z)-10-hydroperoxy-9,12-octadecadienoate to 48% (the wild-type enzyme forms 90% (8E,10R,12Z)-10-hydroperoxy-9,12-octadecadienoate and 10% (8R,9Z,12Z)-8-hydroperoxy-9,12-octadecadienoate)
Aspergillus fumigatus
L384M
increases the relative biosynthesis of (8R,9Z,12Z)-8-hydroperoxy-9,12-octadecadienoate compared to (8E,10R,12Z)-10-hydroperoxy-9,12-octadecadienoate with 3-4% units
Aspergillus fumigatus
L384V
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 22.1% for the mutant enzyme
Aspergillus fumigatus
V388F
the wild-type enzyme forms 90% (8E,10R,12Z)-10-hydroperoxy-9,12-octadecadienoate and 10% (8R,9Z,12Z)-8-hydroperoxy-9,12-octadecadienoate. The mutation increases the formation of (8R,9Z,12Z)-8-hydroperoxy-9,12-octadecadienoate to 36%
Aspergillus fumigatus
V388L
the wild-type enzyme forms 90% (8E,10R,12Z)-10-hydroperoxy-9,12-octadecadienoate and 10% (8R,9Z,12Z)-8-hydroperoxy-9,12-octadecadienoate. The mutation increases the formation of (8R,9Z,12Z)-8-hydroperoxy-9,12-octadecadienoate to 16%

additional information
recombinant enzyme lacks hydroperoxide isomerase activity, but shows low epoxyalcohol synthase activity with biosynthesis of a novel oxylipin, 12S(13R)-epoxy-(10R)-hydroxy-18:1. The enzyme oxygenates 20:4n-6 (all-cis-5,8,11,14-eicosatetraenoic acid) i.e. by hydrogen abstraction at both C-13 and C-10 with formation of two nonconjugated and four cis-trans-conjugated hydroperoxyeicosatetraenoic acid
