IUBMB Comments
A pyridoxal-phosphate protein that requires potassium for activity . In the proteobacterium Acinetobacter baumannii, this enzyme is cotranscribed with the neighbouring ddc gene that also encodes EC, diaminobutyrate decarboxylase. Differs from EC, diaminobutyrate---pyruvate transaminase, which has pyruvate as the amino-group acceptor. This is the first enzyme in the ectoine-biosynthesis pathway, the other enzymes involved being EC, diaminobutyrate acetyltransferase and EC, ectoine synthase [3,4].
