Protein Secondary Structure Flashcards
1
Q
A helices residues/turn, A/residue
A
3.6, 1.5
2
Q
B Sheet A/residue
A
3.5
3
Q
Parallel B helices - polarity and structure
A
Hydrophobic, completely non polar.
Require a helices to connect the C-N ends.
4
Q
Antiparallel B sheets - polarity and structure
A
Amphipathic
A helices not required between termini
5
Q
Singly wound barrel (tertiary structure protein)
A
Parallel B sheet at center
A helices on one side
Amphipathic
6
Q
Doubly wound barrel (tertiary structure protein)
A
Polar exterior, polar interior
7
Q
Apoenzyme
A
Enzyme requiring a cofactor
8
Q
Isoenzyme
A
Enzymes that are different gene products but catalyze the same reaction
Often found in tissues that have altered ideal conditions.
