Bacterial three-component dioxygenase systems consist of reductase and ferredoxin components which transfer electrons from NAD(P)H to a terminal oxygenase. In most cases, the oxygenase consists of two different subunits (alpha and beta). To assess the contributions of the alpha and beta subunits of the oxygenase to substrate specificity, hybrid dioxygenase(More)
Interleukin (IL)-10 is a potent anti-inflammatory and immune-regulatory cytokine. Mice deficient in IL-10 production (IL-10(-/-)) develop a spontaneous inflammatory bowel disease, indicating that IL-10 is an important regulator of the mucosal immune response in vivo. To study the role of IL-10 in the host response to gastric Helicobacter infection, stomachs(More)
The estrogen hormones have been shown to be highly glycogenic as well as lipolytic in nature. It is unknown whether the metabolic actions of estrogens impact upon energy metabolism during exercise. The composition of prior diet, however, does affect exercise energy metabolism. This study examined the influence of menstrual cycle phase (mid-follicular [FP;(More)
The terminal oxygenase component of toluene dioxygenase from Pseudomonas putida F1 is an iron-sulfur protein (ISP(TOL)) that requires mononuclear iron for enzyme activity. Alignment of all available predicted amino acid sequences for the large (alpha) subunits of terminal oxygenases showed a conserved cluster of potential mononuclear iron-binding residues.(More)
A monoclonal antibody designated 302 beta that is specific for the beta subunit of the oxygenase component (ISPTOL) of toluene dioxygenase from Pseudomonas putida F1 was used to prepare an immunoaffinity column. ISPTOL in cell extracts of Escherichia coli JM109(pDTG611) bound to the column, and an enzyme-linked immunosorbent elution-screening assay with(More)
A strategy for controlled pushing is presented for microassembly of 4.5μm polystyrene particles on a flat glass substrate using an atomic force microscope probe tip. Real-time vision based feedback from a CCD camera mounted to a high resolution optical microscope is used to track particle positions relative to the tip and target position. Tip–particle(More)
In this paper, a strategy for controlled pushing is presented for microassembly of 4.5 mum polystyrene particles on a flat glass substrate using an atomic force microscope probe tip.
