The conversion of MI to DCI is achieved by an epimerase
enzyme and its activity was observed to correlate inversely with the degree of insulin resistance.
Those with the most promising results include inhibitors of UDP2 epimerase
, Methionine tRNA synthase, the FtsZ proteins, and NDM-1 beta lactamase.
People with galactosemia, either classic galactosemia or epimerase
deficiency galactosemia, have genetic mutations that decrease their levels of the key enzymes (GALT and GALE) responsible for the metabolism of a common form of dietary sugar.
