Which of the following is the best description of primary
protein structure? ..... ANSWER.....A newly synthesized strand
of amino acids
Cleavage of fructose 1, 6-bisphosphate to dihydroxyacetone
and glyceraldehyde 3-phosphate is achieved by what class of
enzymes? .....
ANSWER.....Lyase
Which of the following amino acid would not be commonly
found in the middle of a an α-helical domain? .....
ANSWER.....Proline
Domains are common structural elements that retain a
particular function within the protein. Which of the following is
an example of a protein domain?
, 4|Page
a) a prosthetic group such as heme
b) irregular coils and loops
c) an arrangement of β-strands connected by α- helixes
d) a single α- helix ..... ANSWER.....An arrangement of β-
strands connected by α-helixes
α helices and β sheets are primarily stabilized by which of the
following interactions? ..... ANSWER.....hydrogen bonding
Hydrogen bonding is the primary stabilizing force in both
secondary structures. In alpha helices the hydrogen bond is
between the carbonyl oxygen group from one peptide bond
and that amide hydrogen from a different peptide bond
approximately amide 4 resides down in the helix. In beta
sheets, the hydrogen bonding is between the carbonyl oxygen
and the amide hydrogen from different peptide strands.
