摘要: The structure of the parasite-encoded G6PD (PfG6PD) may provide clues about relative protection against malaria in humans with glucose-6-phosphate dehydrogenase (G6PD) deficiency. We have cloned Pfg6pd cDNA encoding a predicted 856 amino acid residues polypeptide calculated molecular mass > 94 kDa. sequence is highly homologous to from other organisms. maps as single or low copy number gene chromosome 14. unusually large N-terminus and distance between NADP-binding site G6PD-binding novel for parasite G6PD. differences human proteins could potentially be exploited designing new chemotherapeutic agents.
