| Name |
arachidonate 12-lipoxygenase;
Delta12-lipoxygenase;
12-lipoxygenase;
12Delta-lipoxygenase;
C-12 lipoxygenase;
12S-lipoxygenase;
leukotriene A4 synthase;
LTA4 synthase |
| Class |
Oxidoreductases;
Acting on single donors with O2 as oxidant and incorporation of
oxygen into the substrate (oxygenases). The oxygen incorporated need
not be derived from O2;
With incorporation of two atoms of oxygen
