Gluconobacter oxydans is characterized by its ability to incompletely oxidize carbohydrates and alcohols. The high yields of its oxidation products and complete secretion into the medium make it important for industrial use. We report the finished ge-nome sequence of Gluconobacter oxydans H24, an industrial strain with high L-sorbose productivity. G(More)
The crystal structure of the l-sorbose dehydrogenase (SDH) from Ketogulonicigenium vulgare Y25 has been determined at 2.7 Å resolution using the molecular replacement method. The overall structure of SDH is similar to that of other quinoprotein dehydrogenases; consisting of an eight bladed β-propeller PQQ domain and protrusion loops. We identified a stable(More)
CD47/SIRPα interaction serves as an immune checkpoint for macrophage-mediated phagocytosis. Mouse anti-CD47 blocking antibodies had demonstrated potent efficacy in the treatment of both leukemic and solid tumors in preclinical experimentations, and therefore had moved forward rapidly into clinical trials. However, a fully human blocking antibody, which(More)
l-2-Hydroxyacid dehydrogenase (HDH) from Ketogulonicigenium vulgare Y25 was cloned and overexpressed in Escherichia coli. The protein was purified and crystallized by the sitting-drop vapour-diffusion method with polyethylene glycol 3350 as precipitant. The crystal structure of HDH was determined at 1.64 Å resolution using the molecular replacement method(More)
