Other name(s): pydD (gene name); β-alanine aminotransferase
Systematic name: β-alanine:2-oxoglutarate aminotransferase
Comments: The enzyme, found in many Gram-positive bacteria, participates in the reductive degradation of pyrimidines. In eukaryotes this activity is catalysed by EC 2.6.1.19, 4-aminobutyrate—2-oxoglutarate transaminase.
