Protein
4-aminobutyrate aminotransferase PuuE
Organism
Escherichia coli (strain K12)
Function
Catalyzes the transfer of the amino group from gamma-aminobutyrate (GABA) to alpha-ketoglutarate (KG) to yield succinic semialdehyde (SSA). PuuE is important for utilization of putrescine as the sole nitrogen or carbon source.
Similarity
Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.
