Additional remarks phenotype	Mutant/mutation The mutant lacks expression of TatD Protein (function) The predicted P. falciparum TatD 3D model (without its signal peptide) contains a hydrolase active site surrounded by seven a-helices. The PfTatD domain contains a TIM barrel (COG 1099, multiple domain), which represents a nucleic acid binding region. Furthermore, compared to E. coli TatD, Plasmodium TatD contains an insertion in the middle of the sequence consisting of 73 amino acids (AAs), which marks another feature of the Plasmodium TatDs that is distinct from other microbial homologues, apart from the signal peptide. Phenotype (Slightly) reduced growth rate of blood stages in vivo (and prolonged survial of mice). Additional information Evidence is presented that TatD is exported into the cytoplasm of infected red blood cells. Evidence is presented for deoxyribonuclease/DNA hydrolase activity. Other mutants RMgm-1447: A P. berghei mutant expressing a mutated form of TatD (an aspartic acid-to-alanine mutation at the 352 position of PbTatD).
