Why is rubisco the most important enzyme? What purpose does it serve? Explain why catalase is an important enzyme in mammals. What are the basic mechanisms of enzyme control, and why do they matter? Why is catalase such an important enzyme for bacteria?
The protein’s structure might help generate ideas about what compounds to make next, but then again, it might not. In the end the real numbers from the real biological system are what matter. As a project goes on, those numbers include assays covering pharmacokinetics, metabolism, and to...
What are the basic mechanisms of enzyme control, and why do they matter? How does the concentration of enzymes affect enzyme activity? You have developed a genetically engineered bacterial strain that can make extremely large amounts of human catalase, but so much so that the catalase becomes an...
Proteins are polymers, and yet the language used in describing their thermodynamics and kinetics is most often that of small molecules. Using the terminology and mathematical descriptions of small molecules impedes understanding why proteins have evolved to be big in comparison. Many properties of the ...
Two pathways degrade mRNA: 1) 5′ to 3′ exonuclease reaction mediated by Xrn1p after de-capping of 5'-methylguanosin; 2) 3' to 5' digestion mediated by a nuclear multi-protein complex called exosome after the removal of polyA tail, which does not require the removal of the 5'-cap ...
The reasons for the existence of two gas phase conformers for electrosprayed ions of the large tetradecameric protein complex GroEL are considered. Key features are that: (1) both conformers extrapolate to very similar cross sections in the limit of zero charge; (2) both conformers supercharge...
Does coat/skin color matter? Brown Swiss cattle (a dairy breed) appears to be more predisposed to develop BSE than other breeds, possibly due to the unusually higher number of octapeptide-repeats in the prion protein, shared by the related breed Bruna Alpina [19]. Genetic susceptibility for ...
Although BHT has antiviral properties it does not cure aids. But you are right that the fact that it has antiviral properties has nothing to do with whether it should be used as a food additive. Log in to Reply Dabber August 7, 2017 at 1:03 am Actually kevin is on to something. ...
No the proteinslargely fold on their ownonce they are made. But does Navare not realize that the information that makes the linear structure of a protein into a three-dimensional structure rests largely already in the linear arrangeme...
Why does heating up a protein such as an enzyme cause it to lose function? What are the basic mechanisms of enzyme control, and why do they matter? Is the shape of the enzyme important to its function? What is the lac operon and why is it impor...
