Current Research

Virtually all organisms contain the glycolytic enzyme fructose bisphosphate aldolase. Vertebrates have three distinguishable isoforms of the enzyme; aldolase A, B, and C. Each of these isozymes has different tissue distribution and catalytic properties appropriately for their roles in sugar metabolism. The aldolases have also been implicated in a number of moonlighting functions involved in cell motility, infection, insulin signaling, and endocytosis. It is the goal of the laboratory to understand the biochemical, evolutionary, and developmental mechanisms responsible for the distinguishing features of the various aldolases.

Structure and function of aldolases — The structural and functional details of this ancient and essential glycolytic enzyme are being investigated by structural analysis via x-ray crystallography and electron microscopy of the structures of the different isozymes complexed with substrate or inhibitor.

Characterization of the genetic defects in hereditary fructose intolerance (HFI) — Mutations in the aldolase B gene manifest themselves in HFI, a genetic disorder that can cause liver disease, coma, and death. It is especially problematic for newborn infants at the time they are weaned to fructose-containing foods. A mouse knock-out model is being used to study the disease and mutations from HFI patients of different ethnic groups are being determined.

Evolution of the aldolases — Current projects include the characterization of moonlighting functions that have evolved by oblating these functions with RNAi and mutant forms of the enzyme in tissue culture cells.
