General annotation (Comments)

Function	Catalytic subunit of the tagatose-1,6-bisphosphate aldolase gatYZ, which catalyzes the reversible aldol condensation of dihydroxyacetone phosphate (DHAP or glycerone-phosphate) with glyceraldehyde 3-phosphate (G3P) to produce tagatose 1,6-bisphosphate (TBP). Requires gatZ subunit for full activity and stability. Is involved in the catabolism of galactitol By similarity.
Catalytic activity	D-tagatose 1,6-bisphosphate = glycerone phosphate + D-glyceraldehyde 3-phosphate. HAMAP MF_01294
Cofactor	Binds 1 zinc ion per subunit By similarity.
Pathway	Carbohydrate metabolism; D-tagatose 6-phosphate degradation; D-glyceraldehyde 3-phosphate and glycerone phosphate from D-tagatose 6-phosphate: step 2/2. HAMAP MF_01294
Subunit structure	Forms a complex with gatZ By similarity.
Sequence similarities	Belongs to the class II fructose-bisphosphate aldolase family. TagBP aldolase gatY subfamily.
