2.6.1.76
Activity 2.6.1.76
Description Diaminobutyrate-2-oxoglutarate transaminase
Notes This rather compact family (related to 2.6.1.19_b, GABA aminotransferase) includes bacterial enzymes catalyzing the first step in the ectoine biosynthesis pathway. The enzymes from Halomonas require potassium for function.
