Answer -
b.) a polar, positively charged.
Reson :
Since, the given substrate is very polar, so it will require polar amino acid side chain so that the substare is not replled, And moreover the substare is negatively charged so it will better attacted by a positive charge.
A DNA molecule has many phosphate groups, as shown below What type of amino acid side...
2: Phosphate groups on the backbone of DNA are negatively charged at neutral pH. This suggests that DNA-binding proteins are often enriched in which amino acid? Explain in paragraph. A. E B. G C. K D. L E. W
single letter abbreviation of all amino acids that correspond 4. Amino acids. The side chains of amino acids have a wide spectrum of chemical and physical properties. In each sp. provided below, write the single-letter abbreviations of all amino acids that match the description positively charged side chains at pH 7.4 negatively charged side chains at pH 7.4 negatively charged side chains at pH 12 achiral contains two chiral carbons side chain restricts the rotation of main chain contains carboxamide...
2. Phosphate groups on the backbone of DNA are negatively charged at neutral pH. This suggests that DNA-binding proteins are often enriched in which amino acid? A. E B. G C. K D. L E. W 3. You are studying a particular reaction under conditions in which the AG = 12 kJ/mol. Which of the following statements best describes the equilibrium constant (K.) of this reaction? A. Keq < 0 B. Keq = 0 C. 0 < Keq <1 D....
Even though hydrophobic amino acids tend to be buried in the interior of a globular protein, polar neutral and polar charged amino acids are found in the interior of a globular protein as well. Recall Figure 4.26 of myoglobin. To see how this can happen, consider a model of a generic globular protein (below). The side chains of only seven of the amino acids are shown. 5. "DH" is a side chain that is a hydrogen bond donor "A" is...
10. A mutation in the DNA that codes for a protein has caused an amino acid with a polar charged side chain to be replaced with one that has a polar uncharged side chain. What effect should this have? More likely to be hydrophobic More likely to form an ionic bond More likely to form hydrogen bonds More likely to form disulfide bridges
If a serine protease has a moderately deep but very wide hydrophobic pocket within the active site, which substrate amino acid side chains likely are found there during catalysis. List all that apply. Use single letter codes (in capitals) in alphabetical order.
Answer the following questions based upon a tripeptide sequence with the following amino acids: S L D Serine Leucine Aspartate a) What is the overall charge of the most abundant tripeptide species at neutral pH (pH 7.0)? b) At physiological pH, what is the best desciption of the chemical properties of the side chain of each amino acid? options are: hydrophobic, polar uncharged, negativelly charged, and positively charged c) What is the overall charge of the most abundant tripeptide...
Lecture 3 Identify amino-/carboxy termini, and R-group on amino acid What is chirality? Identify a carbon that is chiral (i.e., has 4 different groups attached) Chiral compounds rotate plane polarized light Memorize amino acid 1) structure, 2) classification (hydrophobic, aliphatic, aromatic, negatively charged, positively charged, polar uncharged) Be able to draw glycine (the generic amino acid) Given an amino acid structure and pKas of ionizable groups, be able to determine the charge at pH 1, pH 14, and pH 7...
What type of covalent bond between amino acid side chains functions in maintaining a polypeptide's specific tertiary structure? disulfide bond ionic bond hydrogen bond peptide bond hydrophobic interaction
(1-7). Shown below are the first steps of protein cleavage as catalyzed by chymotrypsin. The yellow cleft is the active site with side chains showing. Using this diagram, answer the following questions. Onyanion hole 07 1. This reaction involves what types of catalytic mechanisms: covalent catalysis general acid base catalysis metal catalysis A and B B and 5. What is false concerning the middle diagram of the active site shown above? It represents a transition state. Hydrogen bonds from the...
