ENZYME entry: EC 1.14.14.160

Accepted Name
Zealexin A1 synthase.
Alternative Name(s)
CYP71Z18.
Reaction catalysed
(S)-beta-macrocarpene + 3 O(2) + 3 [reduced NADPH--hemoprotein reductase] <=> zealexin A1 + 4 H(2)O + 3 [oxidized NADPH--hemoprotein reductase]
Comment(s)
  • A cytochrome P450 (heme thiolate) enzyme characterized from maize.
  • The enzyme sequentially oxidizes(S)-beta-macrocarpene via alcohol and aldehyde intermediates to form zealexin A1, a maize phytoalexin that provides biochemical protection against fungal infection.
