Document Summary
Laments make up the cytoskeleton inside the cell. Polymers are twisted together to form the actin ber. A lot are enzymes with active sites that catalyze reactions. It is a heme protein and is found in the muscles of aquatic vertebrates like whales. It has a strongly hydrophobic core. they fold via beta turns which contain a lot of proline residues. It is a chain cutting enzyme that cleaves rna chains not dna chains. It is a taco shaped molecule with the active site in a crevice running across the molecule. It has segments of both beta and alpha helices. It contains four disul de bonds and consists of. The disul de bonds helps the protein to survive outside the cell as it is a harsh environment. They are responsible for key cellular processes which include transporters, channels, receptors and enzymes. The lipid bi layer doesn"t allow polar molecules to go across.
