putrescine:2-oxoglutarate aminotransferase
A pyridoxal 5'-phosphate protein [3]. The product, 4-aminobutanal, spontaneously cyclizes to form 1-pyrroline, which may be the actual substrate for EC 1.2.1.19, aminobutyraldehyde dehydrogenase. Cadaverine and spermidine can also act as substrates [3]. Forms part of the arginine-catabolism pathway [2]. cf. EC 2.6.1.113, putrescine---pyruvate transaminase.
