Hycanthone was found to be an inducer of P22 prophage in Salmonella typhimurium LT-2(P22).
The degradation of mammalian ornithine decarboxylase (ODC) (EC 4.1.1.17) by 26 S proteasome, is accelerated by the ODC antizyme (AZ), a trigger protein involved in the specific degradation of eukaryotic ODC. In prokaryotes, AZ has not been found. Previously, we found that in Selenomonas ruminantium, a strictly anaerobic and Gram-negative bacterium, a drastic degradation of lysine decarboxylase ...
Hybrid genetic elements, Mud-P and Mud-Q (collectively, Mud-P22s), have been constructed that carry two-thirds of the temperate Salmonella phage P22 genome sandwiched between the ends of transposon Mu. Insertions of these elements in the Salmonella chromosome generate locked-in P22 prophages that cannot excise. Upon induction (as a consequence of the inactivation of P22 c2 repressor), a locked-...
In a previous study, we found that the p22(phox) subunit of the NADH/NADPH oxidase is overexpressed in vascular smooth muscle cells (VSMCs) from spontaneously hypertensive rats (SHRs) with enhanced vascular production of superoxide anion ((.)O(2)(-)). Thus, we have investigated whether changes in the sequence or activity of the promoter region of p22(phox) gene are present in SHRs. To carry out...
To perform IgG avidity immunoblotting assay for detection of acute toxoplasmosis, 100 serum samples were collected from Tehran, Iran. The presence of Toxoplasma-specific IgG and IgM antibodies were checked by commercial Trinity kit. Samples were categorized in acute and chronic phases of Toxoplasma gondii infection according to IgG avidity ELISA. IgG avidity immunoblotting was performed, and an...
The phagocyte NADPH-dependent oxidase generates superoxide by reducing molecular oxygen through a transmembrane heterodimer known as flavocytochrome b(558) (flavocytochrome b). We investigated the biosynthesis of flavocytochrome b subunits gp91(phox) and p22(phox) to elucidate features of flavocytochrome b processing in myeloid cells. Although the gp91(phox) precursor, gp65, was processed to gp...
Dipole source analyses of early median nerve SEP components 1 obtained from subdural grid recordings
30 31 Objective: The median nerve N20 and P22 SEP components constitute the initial 32 response of the primary somatosensory cortex to somatosensory stimulation of the 33 upper extremity. Knowledge of the underlying generators is important both for basic 34 understanding of the initial sequence of cortical activation and to identify landmarks 35 for eloquent areas to spare in resection planning...
Sweet potato chlorotic stunt virus (SPCSV) is probably the most important virus infecting sweetpotato worldwide, causing severe synergistic disease complexes with several co-infecting viruses. To date only one isolate (Ug), corresponding to the EA strain has been completely sequenced. It was later shown to be unusual in that, in contrast to most isolates, it encoded an additional p22 protein at...
A stepwise addition protocol was developed to display cargo using bacteriophage P22 capsids and the phage decoration (Dec) protein. Three-dimensional image reconstructions of frozen-hydrated samples of P22 particles with nanogold-labeled Dec bound to them revealed the locations of the N- and C-termini of Dec. Each terminus is readily accessible for molecular display through affinity tags such a...
