General Information

General Information Comment Organism
metabolism formylmethionine-independent initiation of translation in apicomplexans, the requirement for an initiation by a specialized tRNA charged with formylmethionine is bypassed in the mitochondrion of these parasites, the formylated methionine used during initiation is deformylated on the nascent peptide by a peptide deformylase Toxoplasma gondii
additional information in Toxoplasma gondii the absence of mitochondrial tRNA genes is compensated for by the import of cytosolic eukaryotic tRNAs. Although all compartments require a complete set of charged tRNAs, the apicomplexan nuclear genomes do not hold sufficient aminoacyl-tRNA synthetase genes to be targeted individually to each compartment. The absence of tRNAMet formyltransferase and peptide deformylase implies that the requirement for a specialized formylmethionyl-tRNAMet for translation initiation is bypassed in the mitochondrion Toxoplasma gondii
