1.13.12.7 | crystallization was achieved using the micro batch technique under oil at 4°C, 2 A resolution structure was determined at -173°C, using isomorphous replacement, the protein is folded into two compact domains. The large N-terminal domain consists of a beta-barrel and two beta-sheets. The sheets are flanked by alpha-helices to form a layered structure, the C-terminal portion forms a distinct domain, separated from the N-terminal domain by a wide cleft |
