The following statements are made to describe the
biosynthetic pathway of IAA;
a) IPA pathway
involves a deamination reaction to form IPA, followed by a decarboxylation
reaction to form indole-3-acetaldehyde (IAld) and then oxidized to IAA by a
specific dehydrogenase
b) IAN pathway is similar to the IPA pathway, except that
the order of the deamination and decarboxylation reactions is reversed, and
different enzymes are involved
c) IAM pathway involves the two enzymes tryptophan monooxygenase and IAM hydrolase
d) In the IAN pathway, tryptophan is first converted to
indole-3-acetaldoxime and then to indole-3-acetonitrile. The enzyme that
converts IAN to IAA is called nitrilase
Which of the following is the correct statements of about the biosynthesis of IAA?
