2.5.1.44
2 putrescine
as partially purified enzymes have been used in the assay the dependence on spermidine for the homospermidine synthesis may have been overlooked. If these enzymes should proof to be spermidine-dependent like other enzymes from plant sources, they must be classified as EC 2.5.1.45
2.5.1.44
2 putrescine
one molecule of putrescine is oxidized by NAD+ to form enzyme-bound 4-aminobutyraldehyde. This intermediate reacts with a second molecule of putrescine to form a Schiff base which is reduced by NADH (formed from NAD+ in the first part of the reaction) to give homospermidine
2.5.1.44
2 putrescine
the enzyme is involved in polyamine biosynthesis pathway
2.5.1.44
more
despite the synthesis of homospermidine, the enzyme also produces 4-aminobutilcadaverine
