The diagnostic value of adenosine deaminase activity in the ascitic fluid of patients with tuberculous peritonitis
… of patients, 3. Establish levels of adenosine deaminase activity which give the best discriminatory information in patients with ascites. 4. Determine what conditions may give rise to false positive or false negative results. 5. Finally, the study was designed to assess the relative diagnostic …

Development of biophysical and Mass Spectrometry Assays for APOBEC3 cytosine deaminases: discovery and validation of cnvalent and non-covalent ligands
APOBEC3 enzymes are cytosine deaminase enzymes that catalyze the conversion of a cytosine base to uracil in single-stranded DNA. There are seven members of the APOBEC3 family – A3A/B/C/DE/F/G/H. APOBEC3 proteins are a part of the innate immune defense system against viral infection, and mutate the …

Characterization and application of type VI-B RNA-targeting CRISPR systems
… system, Casl3b, is an RNA-guided RNase, whose activity can be modulated by the csx genes that often appear in genetic proximity to casl3b. Next, we characterized the behavior of Casl3b and the related enzymes Casl3a and Casl3c in mammalian cells, identifying orthologs of Casl3a and Casl3b with …

The Plant Growth-Promoting Potential of Root-Associated Bacteria from Plants Growing in Stressed Environments
… genotypes and phenotypes including ACC deaminase activity (acds), hydrocarbon degradation (alkB and CYP153), alkaline phosphatase activity (phoD), and nitrogen fixation (nifH). After screening, 28 isolates from 16 genera were subjected to further study in vivo. After using seed …

Restriction of Retrotransposition and Retroviral Infection by RNase L and APOBEC3G
… A3G exhibited elevated cytidine deaminase activity in the presence of RNase L. These results supported a regulatory mechanism for A3G during HIV-1 infections whereby RNase L plays an activating role. Finally in Chapter 5, I determined the in vivo hypermutation characteristic of …

Manipulation of nutrient flow and digestion in defaunated sheep subjected to various dietary regimens
… increased ruminal bacterial density and protease activity against soluble protein, but had no consistent effect on deaminase activity. Defaunation also resulted in lower total perchloric acid-soluble amino-N with similar total free AA concentrations in ruminal fluid.

Direct Amino Acid Uptake by Plants related to Grassland Diversity - methodological and ecological Investigations
… N (Nmin) contents due to insignificant microbial activity or due to poorly developed soils. However, it has also been discussed that amino acid uptake might enable plants to lower intracspecific competition for mineral N and shortcut the microbial mineralization of organic N in systems were …

Molecular Mechanisms and Host Factors Involved in HIV-1 Latency
… expression vector to study the transcriptional activity of the mutated promoter, 2) into non-replicative pNL4 ∆env ∆vif viral expression vector, and 3) into a replicative pNL4-CXCR4 viral vector to study infection and induction by latency reversal agent (LRA) treatment to better understand the …
