General annotation (Comments)

Function

Catalyzes reversively the conversion of L-aspartate beta-semialdehyde (ASA) to L-2,4-diaminobutyrate (DABA) by transamination with L-glutamate By similarity.

Catalytic activity

L-2,4-diaminobutanoate + 2-oxoglutarate = L-aspartate 4-semialdehyde + L-glutamate.

Cofactor

Pyridoxal phosphate By similarity.

Pathway

Amine and polyamine biosynthesis; ectoine biosynthesis; L-ectoine from L-aspartate 4-semialdehyde: step 1/3.

Sequence similarities

Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.
