ENZYME entry: EC 1.14.19.52

Accepted Name
camalexin synthase
Alternative Name(s)
bifunctional dihydrocamalexate synthase/camalexin synthase
CYP71B15
Reaction catalysed
2-(L-cystein-S-yl)-2-(1H-indol-3-yl)-acetonitrile + 2 O2 + 2 reduced [NADPH--hemoprotein reductase] <=> camalexin + CO2 + 2 H(+) + 4 H2O + hydrogen cyanide + 2 oxidized [NADPH--hemoprotein reductase]
Comment(s)
  • This P450 enzyme, which has been characterized from the plant Arabidopsis thaliana, catalyzes the last two steps in the biosynthesis of camalexin, the main phytoalexin in that plant.
  • The enzyme catalyzes two successive oxidation events.
  • During the first of oxidation the enzyme introduces a C-N double bond, liberating hydrogen cyanide, and during the second oxidation it catalyzes a decarboxylation.
  • Formerly EC 1.3.1.n2.
