InterPro: IPR006412 Fructose-bisphosphate aldolase, class II, Calvin cycle subtype

Members of this family are class II examples of the enzyme fructose-bisphosphate aldolase, an enzyme both of glycolysis and (in the opposite direction) of the Calvin cycle of CO2 fixation. A deep split separates the tightly conserved yeast/Escherichia coli/Mycobacterium subtype (all species lacking the Calvin cycle) represented by IPR006411 from a broader group of aldolases that includes both tagatose- and fructose-bisphosphate aldolases. This family represents a distinct, elongated, very well conserved subtype within the latter group. Most species with this aldolase subtype have the Calvin cycle.
