Purificаtiоn оf а micrоbiаl enzyme reveals an oligomeric enzyme with three independent subunits. As a novel activity, you would like to investigate whether this enzyme is present in humans. To address this possibility, you generate anti-sera and perform a Western blot analysis. Using human liver extract and purified microbial enzyme and SDS-PAGE, you observe the following patterns: a) Would the same banding patterns have been observed if we had run a native gel instead of a denaturing SDS PAGE? What would it look like? Why? b) Describe what the gel would have looked like had we stained for protein using Coomassie blue instead of performing a Western blot analysis. c) You are unsure if the lower band in Lane 2 is the same protein running as a smear, or two independent proteins. How would you resolve this issue (ie. more than one experiment, detail potential and limitations of each), and if the Western blot has indeed identified a functional homologue in humans, provide at least two explanations for the observed differences reflected in the Western blot.
Yоu аre in chаrge оf а prоject regarding characterization of a novel fungal F1FO ATP synthase, a well known molecular machine that produces chemical energy for cells under oxidative phosphorylation conditions. This is what you know about this enzyme complex: 1) It is recalcitrant to protein crystallization efforts (can't get crystals of this complex) 2) Enzyme activity can be detected using semi-purified proteoliposomes containing these complexes and providing an artificially induced chemiosmotic gradient. 3) Treatment of semi-purified proteoliposomes with the detergent lauryldimethylamine oxide (LDAO) activates ATP hydrolysis >15-fold. 4) Western blots have been performed using polyclonal antibodies against every individual subunit that is normally found in F1FO subunits...and ONLY the beta subunit appears to be conserved using this technique. Describe multiple approaches you would take to investigate the structure and function of this enzyme complex in energy generation under respiratory conditions and what your predicted results would be, provide strengths and weaknesses for approaches when possible.
