Dictionary » R » Renaturation



(Science: molecular biology) The conversion of denatured protein or dNA to its native configuration.

This is rare for proteins. However, if dNA is denatured by heating the two strands separate and if the heat denatured DNA is then cooled slowly the double stranded helix reforms.

Denaturation and refolding of an enzyme

... but dont get the question and not sure about the answer too, if i am exactly answering the question? Q2.What is the function of cysteine in the renaturation reaction? I think the answer : The side chain on cysteine is thiol participates in enzymatic reactions and act as nucleophile. Cysteine ...

... is heated to 100degrees to separate the strands and then allowed to cool slowly the two strands can find each other and reform the double helix (renaturation.) Consider the following DNA molecule: 5' GCGCGCGCGCGCGC 3' 3' CGCGCGCGCGCGCG 5' If this DNA is heated to 100degrees what would the structure ...

Re: Denaturation of enzymes

So in response to what poison wrote, I need a little more elaboration upon the denaturation and renaturation. You said that most proteins don't reform their natural shape. Could this be due to the fact that you need chaperones and other such helpers to achieve a proteins ...
