Fig. 5From: Characterization of Argonaute nucleases from mesophilic bacteria Paenibacillus borealis and Brevibacillus laterosporusSmall molecule detection by PbAgo and BlAgo and allosteric transcription factors. a Schematic diagram of small molecule detection by PbAgo and BlAgo and allosteric transcription factors. b EMSA with HosA and irregular dsDNA containing the HosA-binding motif. c EMSA evaluation of HosA allosteric activity in the presence of p-HBA. d The denaturing polyacrylamide gel electrophoresis (PAGE) result of PbAgo detecting p-HBA. The denaturing PAGE with irregular dsDNA (lane 1), with irregular dsDNA incubated with HosA (lane 2), with irregular dsDNA incubated with HosA and p-HBA (lane 3), with irregular dsDNA incubated with HosA and PbAgo/gDNA (lane 4), and with irregular dsDNA incubated with HosA, p-HBA, and PbAgo/gDNA (lane 5). e The denaturing PAGE result of BlAgo detected p-HBA.
