Reaction: (1) oleate + O2 = (8E,10S)-10-hydroperoxyoctadeca-8-enoate
(2) linoleate + O2 = (8E,10S,12Z)-10-hydroperoxyoctadeca-8,12-dienoate
(3) α-linolenate + O2 = (8E,10S,12Z,15Z)-10-hydroperoxyoctadeca-8,12,15-trienoate
Other name(s): 10S-DOX; (10S)-dioxygenase; 10S-dioxygenase
Systematic name: oleate:oxygen (10S)-oxidoreductase
Comments: Binds Fe2+. The enzyme isolated from the bacterium Pseudomonas sp. 42A2 has similar activity with all the three Δ9 fatty acids. cf. EC 22.214.171.124, linoleate 10R-lipoxygenase.
