expression of native GND, but not a cytosolic form of GND, in DELTAgnd parasites restores hexosamine-dependent growth. Targeted expression of glucosamine-6-phosphate deaminase, GND, in glycosomes via a canonical C-terminal targeting signal when expressed as a GFP fusion protein | Leishmania major |

malfunction | mutant parasites lacking GND are unable to grow in medium containing amino sugars as sole carbohydrate source and rapidly loose viability, concomitant with the hyper-accumulation of hexosamine-phosphates. Expression of native GND, but not a cytosolic form of GND, in DELTAgnd parasites restored hexosamine-dependent growth, indicating that toxicity is due to depletion of glycosomal pools of ATP. Promastigote and amastigote stages of the DELTAgnd mutant are unable to replicate within macrophages and were either completely cleared or exhibited reduced lesion development in highly susceptible Balb/c mice | Leishmania major |
