General On Fibrous And Structural Proteins Flashcards
Give an example of a fibrous protein in the muscle
Filamentous actin protein
In myofibrils
Micro tubule (tubulin) proteins are also fibrous. What are they made of
13 a helixes filaments
What does tubulin do
It’s a protein which forms a tube from nucleus to membrane and allows transport of things like kinesin protein
Can also bind to anti cancer drugs
Titin is also a fibrous protein- what is its job
In the muscle it prevents filaments sliding too far out
Silk beta sheet is a structural protein Eg in spider webs. What residues is it made of
Alanine and glycine interlocking
A keratin is also a structural protein - in hair, nails etc. What is it made of
2 a helix coils
Can form disulfide bridges Eg in things like nails
What is collagen made of (in skin, bone, teeth)
3 alpha coils in a GLY-PRO-PRO. Sequence
