protein structure and sickle cell anemia Flashcards
Tags proteins to be destroyed
Ubiquaitan
Results in sigmoid shape
cooperation binding
Process made more likely by exercise/high alt/ dehydration
polymerization
2 beta and 2 alpha chains
HbA
2 gamma and 2 alpha chains
HbF
Valine at pos 6
HbS (Sickle Cell Anemia)
8 R alpha helix, single heme group
myoglobin
2 alpha, 2 beta tetrahemic heme
hemoglobin
The form amyloid fibers
PrPsc
Defense Proteins
antibodies, snake venom, MHC proteins
Catalysts proteins
preotease, polumerase, kinases
Transport proteins
hemoglobin, myoglobin, cytochromes
Support Protein
Collagen, Keratin, Fibrin
Bonds between amino acids that generate primary sequence
Peptide bonds
Mostly alpha helices and beta sheets
Secondary
Compound heterozygous sickle cell disease
HbSC
Altered ratio of alpha/beta globin
Thalassemias
Sickle Cell Trait
HbSA
2 alpha, 2 beta, S
HbSS - sickle cell diseae
Point mutation converts this amino a. to valine at pos 6
Glutamate
Build up of amyloid fibers cause this
prion disease
Aspartate, Glutamate, Argine, Lysine, Histidine
Polar Charged AA
Asparagine, Gltamine, Serine, Threonine
Polar uncharged AA
