Three indoleacetaldehyde reductases were purified from cucumber seedlings [ 1,4]. The enzyme requiring NADH as a cofactor occurred in the cytosol one of the two NADPH-specific reductases was associated with a microsomal fraction. The latter reduced phenylacetaldehyde at about half the rate observed for indoleacetaldehyde and exhibited minor activity on some of the aliphatic aldehydes tested. The NADH-requiring enzyme acted only on indoleacetaldehyde and phenylacetaldehyde. None of the three enzymes would catalyze the reverse oxidation of tryptophol.
