What is denaturing of an enzyme? Denaturing enzymes Ifenzymes are exposed to extremes of pH or high temperatures the shape of their active site may change. If this happens then the substrate will no longer fit into the enzymes. This means the key will no longer fit the lock. We say that...
The of an enzyme is an area with a specialized shape and/or set of chemical properties that allows the enzyme to bind with a particular substrate. "Induced fit" means that when a substrate binds to an enzyme's active site: a) it...
To overcome this problem, we developed an Escherichia coli expression system that produces milligram quantities of circularly closed sortase A; efficient enzyme cyclization was achieved by Synechocystis sp. PCC6803 intein-mediated post-translational splicing. The structural integrity of circular sortase A ...

It has been shown that the temperature sensitivity of an enzyme decreases following immobilization [e.g. lipase loses its activity at 50 °C while when immobilized its activity can be maintained in the temperature range of 30–60 °C (Palocci et al. 2007)]; however, the temperature ...
incubated in the solution mixture to analyze the enzyme activities. 2.3. Immunoblotting Proteins from the non-denaturing 2-DE gel were electro- phoretically transferred to polyvinylidene difluoride (PVDF) by using an apparatus as reported for the simulta- neous transfer of proteins from four micro...
spathacea. To investigate the nature of the target structures detected, the chromosomes were treated with RNase A and single strand-specific nuclease S1 before ND-FISH experiments. Signal formation was resistant to standard enzymatic treatment, but sensitive when much higher enzyme concentrations were ...
