Viruses are important pathogens in both marine and fresh water environments. There is a strong interest in using bacteriophages as tracers because of their role as model viruses, since dissolved chemical tracers may not adequately describe the behavior of viruses that are suspended colloids. Despite a large number of studies that examined the transport of bacteriophages in the subsurface enviro...
Two peaks of RNA synthesis (early and late) are directed by bacteriophage P22 in lytic infections of Salmonella typhimurium. Late RNA synthesis is not seen in P22 23- infections; neither early nor late RNA synthesis occurs in P22 24- infections. Genes 23 and 24 of P22 appear to be analogous to genes Q and N of lambda, respectively.
In Selenomonas ruminantium, a strictly anaerobic and gram-negative bacterium, the degradation of lysine/ornithine decarboxylase (LDC/ODC) by ATP-requiring protease(s) is accelerated by the binding of P22, which is a ribosomal protein of this strain. Amino acid sequence alignment of S. ruminantium P22 with the L10 ribosomal proteins of gram-positive and -negative bacteria showed that P22 has a 5...
Bacteriophages offer interesting alternatives to antibodies for the specific capture and detection of pathogenic bacteria onto biosensing surfaces. Procedures for the optimal chemical immobilization of lytic bacteriophages onto surfaces are presented. More specifically, the removal of lysate contaminants from bacteriophage suspensions by size exclusion chromatography significantly increases the...
Bcl10, a CARD-containing protein identified from the t(1;14)(p22;q32) breakpoint in MALT lymphomas, has been shown to induce apoptosis and activate NF-kappaB in vitro. We show that one-third of bcl10-/- embryos developed exencephaly, leading to embryonic lethality. Surprisingly, bcl10-/- cells retained susceptibility to various apoptotic stimuli in vivo and in vitro. However, surviving bcl10-/-...
RBP16 is a guide RNA (gRNA)-binding protein that was shown through immunoprecipitation experiments to interact with approximately 30% of total gRNAs in Trypanosoma brucei mitochondria. To gain insight into the biochemical function of RBP16, we used affinity chromatography and immunoprecipitation to identify RBP16 protein binding partners. By these methods, RBP16 does not appear to stably intera...
The p22(phox) subunit is an essential protein in the activation of NAD(P)H oxidase. Here we report the preliminary characterisation of the human p22(phox) gene promoter. The p22(phox) promoter contains TATA and CCAC boxes and Sp1, gamma-interferon and nuclear factor kappaB sites. We screened for mutations in the p22(phox) promoter and identified a new polymorphism, localised at position -930 fr...
Kinetoplastid RNA (k-RNA) editing is a complex process in the mitochondria of kinetoplastid protozoa, including Trypanosoma brucei, that involves the guide RNA-directed insertion and deletion of uridines from precursor-mRNAs to produce mature, translatable mRNAs. k-RNA editing is performed by multiprotein complexes called editosomes. Additional non-editosome components termed k-RNA-editing acce...
the gene encoding alpha fetoprotein (locus symbol afp) was assigned to rat chromosome 14 at band p21-p22 using fluorescence in situ hybridization method. the present result suggests that there is a conserved syntenic group between human 4q11-q13, mouse 5f-g, and rat 14p21-p22.
