description | <i>Plasmodium</i> is an obligate intracellular parasite that has numerous interactions with different hosts during its elaborate life cycle. This is also the case for the other parasites belonging to the same phylum <i>Apicomplexa</i>. In this study, we bioinformatically identified the components of the multi-synthetase complexes (MSCs) of several <i>Apicomplexa</i> parasites and modelled their assembly using AlphaFold2. It appears that none of these MSCs resemble the two MSCs that we have identified and characterized in <i>Plasmodium</i>. Indeed, tRip, the central protein involved in the association of the two <i>Plasmodium</i> MSCs is different from its homologues, suggesting also that the tRip-dependent import of exogenous tRNAs is not conserved in other apicomplexan parasites. Based on this observation, we searched for obvious differences that could explain the singularity of <i>Plasmodium</i> protein synthesis by comparing tRNA genes and amino acid usage in the different genomes. We noted a contradiction between the large number of asparagine residues used in <i>Plasmodium</i> proteomes and the single gene encoding the tRNA that inserts them into proteins. This observation remains true for all the <i>Plasmodia</i> strains studied, even those that do not contain long asparagine homorepeats. |
