Gene Expression Part 2 Flashcards
1
Q
peptide bond
A
carboxyl with amino acid
2
Q
polypeptide chain
A
aa chain
3
Q
chaperones
A
keep aa chain unfolded
-move aa chain to RER lumen
4
Q
four levels of protein processing
A
1- removal of MET, other clevages
2-alpha helix, beta pleating, gamma turn. proteins help stablaize structure and shape
3-additional folding and bending. chaperones help and stablize
4-interaction of two or more aa chains
5
Q
alpha
A
helix
6
Q
beta
A
sheeting
7
Q
gamma
A
u turn
8
Q
proteosome
A
cell recycling if errors occur like misfolding
9
Q
polysome
A
when 7 ribosomes associate with one mRNA strand allowing multiple copies of same aa chain to be made muliple times
10
Q
proteome
A
all of the proteins found in a particular type of cell
11
Q
post-translational processing
A
form the primary aa chain structure which includes the removal of MET
