Deskripsi
The N-end rule pathway targets substrate proteins for proteasomal degradation. Here, Whiteet al. show that ArabidopsisPLANT CYSTEINE OXIDASEs show dioxygenase activity producing Cys-sulfinic acid at the N-terminus of target proteins, which then act as direct substrates for arginyl transferase.
