Some bacteria like Aquifex aeolicus have Metallo KPS which is a metal-requiring enzyme while others like E.coli have a Non-metallo KPS which does not require a divalent cation for its activity. Kdo-8-P is found in cell walls of higher plants and some green algae. Structural highlights The active site of the metallo KPS contains a divalent cation and the PEP substrate.
