Superfamily: Ubiquitin-protein ligase E3A, N-terminal zinc-binding domain (AZUL)

This superfamily represents the AZUL or amino-terminal zinc-binding domain of ubiquitin E3A ligase (Ube3A, also referred to as E6AP for E6 Associated Protein). is found in eukaryotes, and is an unusual zinc-finger domain. The final cysteine is usually mutated in Angelman syndrome patients. It is likely that AZUL plays a role in Ube3A substrate-recognition. The AZUL domain has a helix-loop-helix architecture with a Zn ion coordinated by four Cys residues arranged in Cys-X(4)-Cys-X(4)-Cys-X(28)-Cys motif PMID:21947926.
