What type of protein secondary structure does the structure shown here (Figure 1) represent?

A. ?-helix

B. ?-sheet

C. ?-helix

D. ?-sheet

E. ?-turn


Sagot :

The protein secondary structure shown in the figure represent α-helix.

The helical structures:

  • The α-helix is the most prevalent kind of secondary structure in proteins.
  • The first person to foresee the presence of α-helices was Linus Pauling.
  • The first protein to have a three-dimensional structure was myoglobin, which was discovered by Max Perutz and John Kendrew using X-ray crystallography.
  • The illustration below shows an instance of a α-helix. "Stick representation" is the name given to this style of protein structural depiction.
  • There are other helical structures in proteins besides the α-helix.  
  • The 3 10α helix, which is supported by hydrogen bonds of the type I i+3), the α-helix, which is supported by hydrogen bonds of the type I i+5), and the left-handed L-α helix are further helical configurations.
  • The 3 10 αhelix has a radius that is smaller than the α-helix, whereas the -helix has a radius that is bigger.
