Purification and Sequencing of DNA Guides from Prokaryotic Argonaute
Authors:  Daan C. Swarts, Edze R. Westra, Stan J. J. Brouns and John van der Oost, date: 11/20/2014, view: 4034, Q&A: 0
Some proteins utilize nucleic acids to guide them to complementary nucleic acid targets. One example is prokaryotic Argonaute protein, which, binds small single stranded DNA molecules as guides (Swarts et al., 2014). This protocol describes ...
Expression and Purification of the Thermus thermophilus Argonaute Protein
Authors:  Daan C. Swarts, Matthijs M. Jore and John van der Oost, date: 10/05/2014, view: 3530, Q&A: 0
The Argonaute protein of Thermus thermophilus (TtAgo) has recently been studied in detail. For its in vitro characterization, TtAgo was purified after heterologous expression in Escherichia coli (E. coli ...

Determination of (p)ppGpp Levels During Stringent Response in Streptomyces coelicolor by Thin Layer Chromatography
Authors:  Smitha Sivapragasam and Anne Grove, date: 11/05/2016, view: 1977, Q&A: 0
The stringent response in bacteria is a stress response that is mediated by the signaling molecules guanosine tetraphosphate and pentaphosphate [(p)ppGpp], alarmones that are also directly related to virulence. Therefore, determination of (p)ppGpp ...

Conjugation Assay for Testing CRISPR-Cas Anti-plasmid Immunity in Staphylococci
Authors:  Forrest C. Walker and Asma Hatoum-Aslan, date: 05/05/2017, view: 1217, Q&A: 0
CRISPR-Cas is a prokaryotic adaptive immune system that prevents uptake of mobile genetic elements such as bacteriophages and plasmids. Plasmid transfer between bacteria is of particular clinical concern due to increasing amounts of antibiotic ...

Transformation of Thermus Species by Natural Competence
Authors:  Alba Blesa and José Berenguer, date: 11/20/2016, view: 1604, Q&A: 0
Many Thermus species harbour genomes scourged with horizontally transferred signatures. Thermus thermophilus (Tth) has been characterized as naturally competent. The transformation protocol described here is based on the ...
