Suppose you are studying the conformation of a monomeric protein that has an unusually high proportion of aromatic acid residues. Compared with a protein of a similar number of amino acids but few aromatic amino acids, would you expect to find fever or more alpha-helices in the protein with a high proportion of aromatic amino acids? Explain.
Homework Answers
No, the aromatic amino acids like phenylalanine, tryptophan, tyrosine are more preferable to form beta- strand conformation. When it is compared with protein that contains lesser numbers of aromatic amino acids, then they will contain the conformation of alpha helix.So, the difference in the amino acids results into the difference in the ability to form secondary structures.
Hope it helps, Good luck !!!!

You have discovered a single cellular eukaryotic organism that has very little vesicle trafficking. You suspect that this may be due to the relatively few formed microtubules that are observed in this species. Upon close examination, you find the microtubules that are present are unusually stable. When looking at an amino acid comparison with human alpha and beta tubulin, you notice that the alpha tubulin is identical, but the beta tubulin is different in the region responsible for GTP hydrolysis....

G alpha z (Gaz) is a protein of 355 amino acids in length. It is synthesized in the cytoplasm and has no signal sequence, nor a start-transfer sequence, nor a nuclear import sequence or patch. After its initial synthesis, Gaz is bound by another protein called a palmitoyltransferase, which covalently attaches a fatty acid called palmitate to a cysteine side chain near the N-terminus of Gaz. This lipid modification allows Gaz to associate with the inner face of the plasma...
