Interaction of rabbit muscle aldolase with phospholipid liposomes. 1979

J Gutowicz, and T Modrzycka

The interaction between rabbit muscle fructose diphosphate aldolase and phospholipid model membranes (liposomes) was studied by measurement of the tryptophan fluorescence of the enzyme. Interaction with liposomes decreases intrinsic fluorescence intensity of the enzyme and shifts the emission wavelength maximum to higher values. The effects appear to be strongly dependent on the nature of the phospholipid polar group and on ionic strength. Also, a reversible modification of specific activity of aldolase upon interaction with liposomes was found. It is postulated that aldolase binds to liposomes mainly by electrostatic interactions and that the binding causes a change in the conformation of the enzyme.

D010743	Phospholipids	Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system.

PROTEIN STRUCTURE, QUATERNARY describes the conformation assumed by multimeric proteins (aggregates of more than one polypeptide chain).

D005634	Fructose-Bisphosphate Aldolase	An enzyme of the lyase class that catalyzes the cleavage of fructose 1,6-biphosphate to form dihydroxyacetone phosphate and glyceraldehyde 3-phosphate. The enzyme also acts on (3S,4R)-ketose 1-phosphates. The yeast and bacterial enzymes are zinc proteins. (Enzyme Nomenclature, 1992) E.C. 4.1.2.13.
