WebArg-1 catabolizes L-arginine to urea and ornithine, the latter of which is a precursor for amino acid and polyamine synthesis. ROP16-induced Arg-1 could serve to promote parasite replication inasmuch as Toxoplasma lacks enzymes required for polyamine synthesis and therefore must scavenge these molecules from the host cell (Cook et al., 2007). WebPolyamine metabolism is also associated with many aspects of immune function. In particular, polyamine metabolism is enhanced in activated T-cells as a function of c-Myc induction of ornithine decarboxylase (ODC), which converts the non-proteinogenic amino acid ornithine to putrescine (Nilsson et al., 2005 ).
