Catalyzes the synthesis of N-((2S)-2-amino-2-carboxyethyl)-L-glutamate (ACEGA) from O-phospho-L-serine and L-glutamate. Involved in the biosynthesis of L-2,3-diaminopropionic acid (L-Dap), a precursor of staphyloferrin B and antibiotics.

Belongs to the cysteine synthase/cystathionine beta-synthase family. SbnA subfamily.
