(Research Problem) The Nature and Roles of Linear Motifs in Proteins In addition to domains and modules, there are other significant sequence patterns in proteins—known as linear motifs—that are associated with a particular function. Consult the biochemical literature to answer the following questions: 1. What are linear motifs? 2. How are they different from domains?. 3. What are their functions? 4. How can they be characterized? 5. There are several papers that are good starting points for this problem. Neduva, V., and Russell, R., 2005. Linear motifs: evolutionary interaction switches.

Solving the Sequence of an Oligopeptide From Sequence Analysis Data Amino acid analysis of a decapeptide revealed the presence of the following products: The following facts were observed: Neither car boxy peptidase A nor B treatment of the- decapeptide had any effect. Trypsin treatment yielded two tetrapcptides and free Lys. Clostripain treatment yielded a tetrapcptide and a hexapeptidc. Cyanogen bromide treatment yielded an octapeptide and a dipeptide of sequence NP (using the one-letter codes). Chymotrypsin treatment yielded two tripeptides and a telrapeptide. The N-terminal chymotryptic peptide had a net charge of — 1 at neutral pi I and a net charge of —3 al pH 12.

The Sequence Relationship Between an Antisense RNA Strand and Its Template DNA Strand The DNA strand that is complementary to the template strand copied by RNA polymerase during transcription has a nucleotide sequence identical to that of the RNA being synthesized (except T residues are found in the DNA strand at sites where U residues occur in the RNA). An RNA transcribed from this nontem-plate DNA strand would be complementary to the mRNA synthesized by RNA polymerase. Such an RNA is called antisense RNA because its base sequence is complementary to the “sense mRNA. One strategy to thwart the deleterious effects of genes activated in disease slates (such as cancer) is to generate antisense RNAs in affected cells. These antisense RNAs would form double-stranded hybrids with mRNAs transcribed from the activated genes and prevent their translation into protein. Suppose transcription of a cancer-activated gene yielded an mRNA whose sequence included the segment 5’-UACGUCUAAGCUGA. What is the corresponding nucleotide sequence (5’ The template strand in a DNA duplex that might be introduced into these cells so that an untisense RNA could be transcribed from it?arrow_forwardAnswers to all problems are at the end of this book.
