Fructose‐1,6‐bisphosphate aldolase (Fru‐P 2 A) from a psychrophilic marine bacterium was found to be Class II aldolase based on activation by K + , activation by divalent cations, inactivation by EDTA, low molecular weight, and similar values for K m , V max , and A RRHENIUS activation energy. This enzyme was not markedly different in amino acid composition from the enzymes from mesophilic and thermophilic organisms, yet it has unusual thermal properties.
