The 2 mechanisms to alter protein shape are allosteric and covalent modulation.
Allosteric: If the protein contains 2 binding sites, the noncovalent binding of a ligand to one site can alter the shape & characteristics of the other site.
-One binding site on an allosteric protein, the functional site, carries out the proteins physiological functions.
-The other binding site is the regulatory site, and the ligand that binds to it is called the modulator molecule because it changes the shape!
Covalent: Covalent bonding of charged chemical groups to some of the proteins side chains changes the shape and characteristics of the protein. Usually a phosphate group is covalently bonded, in the reaction called phosphorylation.
What else can I help you with?
Is Hydrogen sulfide covalent or ionic?
It is covalent due to the small electronegativity difference between hydrogen and sulfur.
What type of electronegativity difference exists between atoms in a covalent bond?
In a covalent bond, atoms with a small electronegativity difference share electrons almost equally, creating a nonpolar covalent bond. When there is a larger electronegativity difference, one atom pulls the shared electrons more strongly, resulting in a polar covalent bond.
Is the bond between fluorine and chlorine nonpolar covalent?
The electronegativity of oxygen is 3.44 and for fluorine it is 3.98. The difference in electronegativities is 0.54, so the bond between fluorine and oxygen is polar covalent.
How can you figure out if a bond is ionic or covalent?
The difference in electronegativity between the atoms that are bonded. A difference of more than about 1.7 indicates that the bond will be ionic. Health warning - this is only a rule of thumb.
What values best classifies a bond between 2 atoms as being covalent?
An electronegativity difference of less that 1.7 between the atoms
What is the difference between space vector modulation and pulse width modulation?
There is no difference.
What is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
What is the difference between pulse code modulation and delta modulation?
The difference between pulse code modulation and delta modulation is that pulse code modulation is a method of encoding audio information digitally while delta modulation is a method that converts analog to digital signal.
What is the difference between analog and digital modulation Does it depends on baseband signal?
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
Difference between delta modulation and differential pulse code modulation?
Delta modulation is not a type of quality conversion and runs on digital-to-analog, analog-to-digital. Differential pulse code modulation has a higher quality of conversion and runs on a 1-bit data stream.
What is the difference between ionic and covalent?
Covalent compounds are more flammable when compared to ionic compounds.Ionic compounds are more soluble in water than covalent compounds.for more go to: difference between . net
Difference between digital transmission and digital modulation?
The Difference of two is only first digital has a transmission and second digital has modulation.....thats all....i think that's too clear ha...
Is Hydrogen sulfide covalent or ionic?
It is covalent due to the small electronegativity difference between hydrogen and sulfur.
Compare pulse code modulation and delta modulation?
delta modulation refers to the procedure of encoding and thereby transmitting only the difference between consecutive samples instead of sending each of the samples themselves. This method is useful only when the vaiation in the amplitude of the signal is small, otherwise, it leads to a phenomenon called "slope overload".Pulse code modulation is the procedure where each of the levels of an analog signal is assigned a value closest ro a quantizer level used to quantize the signal...Another method of PCM that can be confused with Delta Modulation is the D(ifferential)PCM. Here, the difference between the signals is encoded based on its magnitude..
What is the difference between am raido and FM radio?
A: AM radio is an Amplitude Modulation transmission . Meaning it has fix frequency but it is modulated by the signal. FM Frequency Modulation the frequency is modulated by the signal
What type of electronegativity difference exists between atoms in a covalent bond?
In a covalent bond, atoms with a small electronegativity difference share electrons almost equally, creating a nonpolar covalent bond. When there is a larger electronegativity difference, one atom pulls the shared electrons more strongly, resulting in a polar covalent bond.
What is the difference between a noncompetitive inhibitor and an allosteric inhibitor in enzyme regulation?
A noncompetitive inhibitor binds to an enzyme at a site other than the active site, while an allosteric inhibitor binds to a different site on the enzyme, causing a change in the enzyme's shape and reducing its activity.
