Keniston, Richard Chace published the artcilePolyamine-pyridoxal 5′-phosphate interaction: effects of pH and phosphate concentration in Schiff’s base formation, Product Details of C3H12Cl2N2, the publication is Physiological Chemistry and Physics (1979), 11(5), 465-70, database is CAplus.
The polyamines, spermine, spermidine, and putrescine, reacted rapidly with pyridoxal phosphate (I) in aqueous solution at neutral pH to yield Schiff bases. At high pH, spermine and spermidine cyclized with I to give aldamines. The rate of reaction of polyamines with I was inversely proportional to the phosphate concentration of the buffer and directly proportional to the pH over the physiol. range (pH 6.0-8.0). Spermine reacted faster, and at a lower molar concentration, than any other amine or amino acid tested.
