A recombinant form of D-3-hydroxybutyrate dehydrogenase (EC 1.1.1.30) from Pseudomonas fragi has been crystallized by the hanging-drop method using PEG 3000 as a precipitating agent. The crystals belong to the orthorhombic group P2(1)2(1)2, with unit-cell parameters a = 64.3, b = 99.0, c = 110.2 A. The crystals are most likely to contain two tetrameric subunits in the asymmetric unit, with a VM...
BACKGROUND To date, there is no safe and effective hemoglobin-based oxygen carrier (HBOC) to substitute for erythrocyte transfusion. It is uncertain whether a deficiency of endothelial nitric oxide bioavailability (endothelial dysfunction) prevents or augments HBOC-induced vasoconstriction. METHODS Hemodynamic effects of infusion of PolyHeme (1.08 g hemoglobin/kg; Northfield Laboratories, Eva...
BACKGROUND Uricase has proven therapeutic value in treating hyperuricemia but sufficient reduction of its immunogenicity may be the largest obstacle to its chronic use. In this study, canine uricase was modified with 5 kDa mPEG-SPA and the impact of large aggregated uricases and cross-linked conjugates induced by difunctional PEG diol on immunogenicity was investigated. METHODS AND FINDINGS R...
