Enzymatic and Structural Characterization of the Naegleria fowleri Glucokinase.

ABSTRACT: Infection with the free-living amoeba Naegleria fowleri leads to life-threatening primary amoebic meningoencephalitis. Efficacious treatment options for these infections are limited, and the mortality rate is very high (∼98%). Parasite metabolism may provide suitable targets for therapeutic design. Like most other organisms, glucose metabolism is critical for parasite viability, being required for growth in culture. The first enzyme required for glucose metabolism is typically a hexokinase (HK), which transfers a phosphate from ATP to glucose. The products of this enzyme are required for both glycolysis and the pentose phosphate pathway. However, the N. fowleri genome lacks an obvious HK homolog and instead harbors a glucokinase (Glck). The N. fowleri Glck (NfGlck) sha
