CC   -!- CATALYTIC ACTIVITY: D-galactose 6-phosphate = D-tagatose 6-
CC       phosphate.
CC   -!- PATHWAY: Carbohydrate metabolism; galactose degradation; D-
CC       tagatose 6-phosphate from D-galactose 6-phosphate: step 1/1.
CC   -!- SUBUNIT: Heteromultimeric protein consisting of lacA and lacB (By
CC       similarity).
CC   -!- SIMILARITY: Belongs to the lacAB/rpiB family.
