CC -!- FUNCTION: Catalytic subunit of the tagatose-1,6-bisphosphate aldolase
CC KbaYZ, which catalyzes the reversible aldol condensation of
CC dihydroxyacetone phosphate (DHAP or glycerone-phosphate) with
CC glyceraldehyde 3-phosphate (G3P) to produce tagatose 1,6-bisphosphate
CC (TBP). Requires KbaZ subunit for full activity and stability.
CC {ECO:0000255|HAMAP-Rule:MF_01293}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-tagatofuranose 1,6-bisphosphate = D-glyceraldehyde 3-
CC phosphate + dihydroxyacetone phosphate; Xref=Rhea:RHEA:22948,
CC ChEBI:CHEBI:57642, ChEBI:CHEBI:58694, ChEBI:CHEBI:59776; EC=4.1.2.40;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01293};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01293};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01293};
CC -!- PATHWAY: Carbohydrate metabolism; D-tagatose 6-phosphate degradation;
CC D-glyceraldehyde 3-phosphate and glycerone phosphate from D-tagatose 6-
CC phosphate: step 2/2. {ECO:0000255|HAMAP-Rule:MF_01293}.
CC -!- SUBUNIT: Homotetramer. Forms a complex with KbaZ. {ECO:0000255|HAMAP-
CC Rule:MF_01293}.
CC -!- SIMILARITY: Belongs to the class II fructose-bisphosphate aldolase
CC family. TagBP aldolase KbaY subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_01293}.
