Figure 4From: Tv-RIO1 – an atypical protein kinase from the parasitic nematode Trichostrongylus vitrinusHomology model of the Tv -RIO1 protein from Trichostrongylus vitrinus. The loop in red indicates the region of dissimilarity between Tv-RIO1 and Af-RIO1 from Archaeoglobus fulgidus. The P-loop required for the binding to phosphate is shown in blue. Catalytic residues (Asn 281, Asp 276 and Asp 293) and the highly conserved Tyr 280 are indicated by yellow sticks.Back to article page
