Which of the following best describes ANSWER Interactions between α-helices and β sheets
tertiary structure? to form a domain.
Tertiary structure is best described as the entire three-
dimensional conformation of a polypeptide including
how secondary structural features - helices, sheets,
bends, turns and loops - assemble to form domains
and how these domains relate.
Which of the following best describes ANSWER A planar porphyrin ring that binds iron
the structure of heme?
Heme is a prosthetic group that is planar and has a
bound iron center.
Covalent catalysis is used by many ANSWER Valine
enzymes to cleave peptide bonds.
Which of the The R-group on valine does not have an active group
following amino acids would not to participate in covalent catalysis. The most
facilitate this type of catalysis? (Think commonly
of the structure of the R-group of participating amino acids are cysteine, serine and
these amino acids) histidine.
An enzyme has a mutation within the ANSWER The enzyme will not be able to form the
substrate binding site that reduces transition state complex
the binding of the coenzyme needed
for Loss of coenzyme binding will result in inability to form
covalent catalysis. Which of the the transition substrate enzyme complex.
following is likely to result as a
consequence of this
mutation?
Movement of ammonia from an ANSWER Transferases
amino acid to an α-keto acid involves
a family of enzymes best categorized Amino transferases are commonly used in the
as which of the following?
movement of ammonia and use the covalent catalysis
"ping-pong method".
