Often, AIMPs contain an N-terminal glutathione S-transferase (GST)-like domain and a C-terminal OB-fold tRNA-binding domain. Recently, the apicomplexan-specific Plasmodium falciparum p43 protein (Pfp43) has been annotated as an AIMP and its tRNA binding, tRNA import and membrane association have been characterized. The crystal structures of both the N- and C-terminal domains of the Plasmodium vivax p43 protein (Pvp43), which is an ortholog of Pfp43, have been resolved. Analyses reveal the overall oligomeric structure of Pvp43 and highlight several notable features that show Pvp43 to be a soluble, cytosolic protein. The dimeric assembly of the N-terminal GST-like domain of Pvp43 differs significantly from canonical GST dimers, and it is tied to the C-terminal tRNA-binding domain via a linker region. This work therefore establishes a framework for dissecting the additional roles of p43 orthologs in eukaryotic multi-protein MARS complexes.
