Chapter 1, Problem 12P
Figure 1.6 shows the amino acid sequences of parts of the cytochrome c proteins from several different organisms. Some of these amino acids are highlighted in dark orange, some in light orange, and some are not highlighted at all. Which of these three classes of amino acids is likely to be most important for the biochemical function of cytochrome c proteins?

1. A) Explain this statement, “Most enzymes are gene-encoded proteins, but most enzymes are not only
protein". B) You recently isolated a new enzyme in your lab, and you named it "lipidase 1120". As a
temporary name, this is fine. Who is responsible for assigning a formal name, and on what criteria will that
name be assigned?
Idris has successfully extracted enzymatic proteins from the fish viscera (intestines and stomach). After homogenization and centrifugation, he managed to pool the crude enzyme extract. He is characterizing the enzymes. Please help Idris by answering the followingquestions:The experiments I conducted showed that one of the enzymes was successful in degrading casein.(a). Which family of enzyme is it from?(b). What is the possible name of this enzyme and why?
Pro-CHEMBIO peptide is a large peptide sequence with three disulfide bonds (indicated by the lines between cysteine residues). CHEMBIO Protease cleaves amide bonds between two basic amino acid residues to give the final peptide that is active in the body.
The products of this protease reaction are:
1. Two chains that make up active CHEMBIO peptide, which contain the N- and C-terminus sections of the original Pro-CHEMBIO molecule
2. A separate inactive peptide
What if instead of CHEMBIO Protease, this peptide was cleaved by trypsin? Indicate the cleavage locations on the structure below.

- PLP is a cofactor for a number of enzymes involved in amino acid metabolism. Give an example of reaction in which PLP participates in cleavage of the a, b, and c bonds of an amino acid, as diagrammed in shown Fig.arrow_forwardXylose racemase is a bacterial enzyme that converts the sugar D-xylose to L-xylose, which is needed in small amounts for the bacterial cell wall. The active site of xylose racemase includes a Y residue with a pKa = 7.2. The altered pKa of this residue, compared to its pKa in bulk water, is due largely to the presence of a nearby charged amino acid residue in the active site. Which is a likely explanation for the shift in the Y residue pka? The negative charge in a nearby E residue could stabilize a deprotonated Y residue. The negative charge in a nearby D residue could destabilize a protonated Y residue. The positive charge in a nearby K residue could stabilize a deprotonated Y residue. The positive charge in a nearby R residue could destabilize a deprotonated Y residue.arrow_forwardLactose permease, a protein of E. coli, is composed of a singlepolypeptide that is 417 amino acids in length. By convention, theamino acids within a polypeptide are numbered from the aminoterminalend to the carboxyl-terminal end. Are the following questionsabout lactose permease true or false?A. Because the sixty-fourth amino acid is glycine and the sixty- eighth amino acid is aspartic acid, the codon for glycine,64, is closer to the 3′ end of the mRNA than the codon for aspartic acid, 68.B. The mRNA that encodes lactose permease must be greater than1241 nucleotides in length.arrow_forward
- When performing his experiments on protein refolding, Christian Anfinsen obtained a quite different result when reduced ribonuclease was reoxidized while it was still in 8 M urea and the preparation was then dialyzed to remove the urea. Ribonuclease reoxidized in this way had only 1% of the enzymatic activity of the native protein. Why were the outcomes so different when reduced ribonuclease was reoxidized in the presence and absence of urea?arrow_forwardFour proteins Cytochrome C (pI=10.2) Myoglobin (pI=7.2), Hemoglobin (pI = 6.8) and Serum Albumin (pI= 4.8) were used in our gel electrophoresis lab exercise.

- Pompe disease is a rare genetic condition resulting from a deficiency of the protein alpha-glucosidase. The following three mutations are among the 100+ mutations known or suspected of causing the disease. Context is provided in parentheses.

The question is: are they related or not? i.e. Are the structures essentially the same? Often you can get similar reactions from proteins thatevolved from a common ancestor (e.g., trypsin and chymotrypsin). Sometimes the samereaction can be catalyzed by proteins with very different evolutionary origins and with verydifferent structures (e.g., trypsin and subtilisin). Your job is to decide if these proteins have fundamentally different folds or if they have basically the same fold. Briefly justify your answer.1.
