Protein sequencing I. Determine the sequence of hexapeptide based on the following data. Note: When the sequence is not known, a comma separates the amino acids. Amino acid composition: (2R,A,S,V,Y) N-terminal analysis of the hexapeptide: A Trypsin digestion: (R,A,V) and (R,S,Y) Carboxypeptidase digestion: No digestion. Chymotrypsin digestion: (A,R,V,Y) and (R,S)
The restriction enzyme AluI cleaves at the sequence 5 -AGCT-3 , and NotI cleaves at 5 -GCGGCCGC-3 . What would be the average distance between cleavage sites for each enzyme on digestion of double-stranded DNA?
The red line on the following graph shows the fluidity of the fatty acids of a phospholipid bilayer as a function of temperature. The blue line shows the fluidity in the presence of cholesterol.
