Question
Chapter 32, Problem 11P
Interpretation Introduction
Interpretation:
The reason for use of alpha helices in the membrane-spanning for the G-protein-coupled receptors needs to be explained.
Concept Introduction :
The structure of alpha-helix is a polypeptide chain like a coiled rod giving a spring like structure. These polypeptide chains are bonded together with hydrogen bonds. The beta strands are responsible for bonding in beta-pleated sheets where they linked in lateral manner with hydrogen bonds resulting formation of a backbone. The number of amino acids involved in beta strand or chain formation is from 3-10.

The titration of di-, tri-, and larger oligopeptides of alanine also shows the ionization of only two functional groups, although the experimental pK values are different. The table summarizes the trend in pK values.

- Electrophoresis Macmillan Learning Chymotrypsin is a protease with a molecular mass of 25.6 kDa. The figure shows a stained SDS polyacrylamide gel with a single band in lane I and three bands of lower molecular weight in lane 2. Lane I contains a preparation of chymotrypsin and lane 2 contains chymotrypsin pre-treated with performic acid. 1 2 Why does performic acid treatment of chymotrypsin generate three bands in lane 2? ° Chymotrypsin self-digests on the carboxyl-terminal side of phenylalanine, tryptophan, or tyrosine residues. The three peptides are impurities in the original chymotrypsin sample. Performic acid cleaves proteins on the carboxyl-terminal side of lysine and arginine residues. Performic acid cleaves the disulfide bonds holding together the three subunits of chymotrypsin. Correct Answerarrow_forwardExtracts from the bacterium Bacillus brevis contain a peptide with antibiotic properties. This peptide forms complexes with metal ions and seems to disrupt ion transport across the cell membranes of other bacterial species, leading to bacterial death. The structure of the peptide has been determined from a series of observations. (a) Complete acid hydrolysis of the peptide, followed by amino acid analysis, yielded equimolar amounts of Leu, Orn, Phe, Pro, and Val. Orn is ornithine, an amino acid not present in proteins but present in some peptides. Orn has the structure H 'H,N-CH, - CH2 CH2 CH2 - C - COO- NH, (b) The molecular weight of the peptide is approximately 1,200 Da. (c) The peptide failed to undergo hydrolysis when treated with the enzyme carboxypeptidase. This enzyme catalyzes the hydrolysis of the carboxyl-terminal residue of a polypeptide unless the residue is Pro or the peptide does not contain a free carboxyl group.
