Intramolecular disulfide bond - Answer 2 C
(1 C can form disulfide bonds with other C groups)
Phosphorylated - Answer S, T, Y
Alpha helix breakers - Answer P
Bulky clusters: Y, W, L, V, F
Charged clusters: K, R, H, D, E
Ionizable side chains - Answer R, K, Y, C, H, E, D
Scurvy - Answer Caused by impaired hydroxylation of lysine and proline causing
unstable triple helices due to vitamin C deficiency.
, Prion disease - Answer Proteins are refolded from α-helix into β-sheet form, producing
long insoluble fibrils and a loss of function.
Alzheimer's disease - Answer Abnormal cleavage of the hydrophobic section of a
protein, which causes aggregation into long, insoluble neurotoxic fibrils.
Ostegenesis imperfecta - Answer Mutation of Gly-X-Y repeating sequences into bulky
amino acids, preventing assembly of helices into a mature collagen fiber (brittle bone
disease).
Respiratory acidosis - Answer Caused by a sharp increase of carbon dioxide in the blood.
Sickle cell anemia - Answer The aggregation of a mutated hemoglobin protein caused by
the substitution of glutamic acid to valine.
Ehlers-Danlos syndrome - Answer Proteins are refolded from α-helix into β-sheet form,
producing long insoluble fibrils and a loss of function.
Oxidoreductase - Answer Transfer electrons between molecules; catalyze oxidation-
reduction reactions.
Transferase - Answer Transfer functional groups between molecules.
Hydrolyase - Answer Cleaves molecules by the addition of water.
Lyase - Answer Adds atoms or functional groups to a double bond or removes them to
form double bonds.
