Abstract:
3-Nitro-1-propanamine is a close structural analog of the neuro-transmitter GABA. The nitro compound is a good substrate for the GABA aminotransferase from porcine brain. However, it inactivates the GABA aminotransferase from GABA-grown Pseudomonas fluorescens in a slowly reversible reaction. Both enzymes are inactivated by the homolog 4-nitro-1-butanamine.
