Both L-ornithine and L-arginine were found to be poor substrates for lentil amine oxidase. L-Ornithine was oxidized to glutamate-5-semialdehyde and ammonia, in similar manner as usual substrates. Glutamate-5-semialdehyde spontaneously cyclizes to Δ1-pyrroline-5-carboxylic acid. Arginine is oxidized by an unusual mechanism yielding glutamate-5-semialdehyde, ammonia, and urea as reaction products.
