|L-valine + 2 O(2) + 2 [reduced NADPH--hemoprotein reductase] <=> (E)-2-methylpropanal oxime + 2 [oxidized NADPH--hemoprotein reductase] + CO(2) + 3 H(2)O|
- This enzyme catalyzes two successive N-hydroxylations of L-valine,
the committed step in the biosynthesis of the cyanogenic glucoside
linamarin in Manihot esculenta (cassava).
- The product of the two hydroxylations, N,N-dihydroxy-L-valine,
is labile and undergoes dehydration and decarboxylation that produce
the (E) isomer of the oxime.
- It is still not known whether the decarboxylation is spontaneous or
catalyzed by the enzyme.
- The enzyme can also accept L-isoleucine as substrate, with a lower
- It is different from EC 22.214.171.124.
- Formerly EC 126.96.36.199.
