The Skp1 modification pathway. (A) The hydroxylation/glycosylation pathway in T. gondii. A homologous pathway is predicted in P. ultimum. PgtA-N and PgtA-C refer to separate domains of the same protein. (B) Domain diagrams of PhyA and Gnt1 proteins from D. discoideum (van der Wel et al. 2005; van der Wel et al. 2002b), T. gondii (Xu et al. 2012; Rahman et al. 2016) and P. ultimum. The prediction for P. ultimum is based on genomic sequence data and amino acid homology of the translated sequence (Figure S1). Colored boxes refer to regions of substantial homology.
