The catalytic subunits GatY/KbaY alone are sufficient to show aldolase activity and contain most or all of the residues that have been identified as essential in substrate/product recognition and catalysis for class II aldolases [1, 2]. However, these aldolases differ from other Class II aldolases (which are homodimeric enzymes) in that they require subunits GatZ/KbaZ for full activity and for good in vivo and in vitro stability. The Z subunits alone do not show any aldolase activity [1]. This entry represents GatZ and KbaZ subunits. This entry also includes the D-tagatose 6-phosphate 4-epimerase Atu3167 from Agrobacterium fabrum which catalyzes the epimerization of D-tagatose 6-phosphate to D-fructose 6-phosphate [3]. It should be noted that the previous suggestion of a tagatose 6P-kinase function for other members of this family has been debated [4, 1, 5].
