Description | Escherichia coli and other enteric bacteria contain two closely related D-tagatose 1,6-bisphosphate (TagBP)-specific aldolases involved in catabolism of galactitol (genes gatY gatZ) and of N-acetyl-galactosamine and D-galactosamine (genes kbaY, kbaZ, also called agaY, agaZ). 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 [ , ]. 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 []. It should be noted that the previous suggestion of a tagatose 6P-kinase function for AgaZ [] and other members of this family have been debated [, , ].This entry represents the GatZ proteins. |
