Definition

The glyoxalase system consists of glutathione and two enzymes that catalyze the conversion of 2-oxoaldehydes to 2-hydroxycarboxylic acids. For example, the cytosolic glyoxalase systems of malaria parasites and their hosts convert harmful glycolysis-derived methylglyoxal to d-lactic acid. Moreover, the host-parasite unit comprises additional glyoxalase isoforms with peculiar properties suggesting other, yet uncharacterized, physiological functions.

Introduction

According to current theories the glyoxalase system is a metabolic adaptation to reactive 2-oxoaldehydes (2-OAs), which are formed as by-products during glycolysis and other metabolic pathways. Electrophilic 2-OAs are harmful because of their ability to react with physiological nucleophiles resulting in modified proteins and nucleic acids. Such modified biomolecules are summarized as advanced glycation endproducts...
