Function
Involved in the biosynthesis of ectoine ((S)-2-methyl-1,4,5,6-tetrahydropyrimidine-4-carboxylic acid) which is a highly soluble organic osmolyte, called compatible solute, use to avoid excessive water efflux, plasmolysis, molecular crowding of the cytoplasm, and cessation of growth in high salinity environments. Catalyzes the deacetylation of N-alpha-acetyl-L-2,4-diaminobutyrate (N-alpha-Ac-DABA) to yield L-2,4-diaminobutyrate (DABA).
