Schematic representation of the primary structure of latent and active cgAUS1. The catalytically active main core is coloured red, with the copper-binding sites coloured blue, and the C-terminal domain is shown in green. Owing to a disulfide linkage of the main core to the C-terminal domain (represented by yellow connectors), the proteolytically activated enzyme possesses a remaining C-terminal peptide (Molitor et al., 2015). The tyrosine residue Tyr230 of active cgAUS1 is partially phosphorylated or sulfated (displayed by a violet rectangle) |
