Questions #20-23 pertain to the SDS-PAGE images shown below. Gel A (left) is a non-reducing SDS-PAGE. Gel B (right) is a reducing SDS-PAGE. The M lanes contain molecular weight markers. Lanes 1, 2, &3 were loaded with equal volumes of a purified preparation of Protein X. Lane 4 was loaded with an equal volume of a crude preparation of Protein X (prior to purification). M...

Protein phosphorylation to amino acid residues is commonly involved with all of the following except A regulation of transcription by extracellular signal molecules B. enzyme activation c activation of G-protein-linked receptors p. activation of protein kinase molecules
A protein biochemist attempted to determine the amino acid sequence of a decapeptide. Use the results from the trypsin, chymotrypsin, and cyanogen bromide treatments to suggest the amino acid sequence of this decapeptide. Trypsin digestion gave two fragments with the following residues (not in order): T1: Ala, Arg, Phe, Pro, Thr, Trp, Tyr T2: Lys, Met, Val Chymotrypsin digestion gave three fragments with the following residues (not in order): CT1: Ala, Phe CT2: Pro, Arg CT3: Thr, Trp CT4: Lys,...
Calculate the approximate number of residues of Rubisco, which is involved in carbon fixation in plants, with a monomeric molecular weight of 55 kDa
anyone can help me with it?
A protein biochemist attempted to determine the amino acid sequence of a decapeptide. Use the results from the trypsin, chymotrypsin, and cyanogen bromide treatments to suggest the amino acid sequence of this decapeptide. Trypsin digestion gave two fragments with multiple residues (not in order): • T1: Ala, Arg, Phe, Gly, Thr, Trp, Tyr • T2: Lys, Met, Val Chymotrypsin digestion gave four fragments with multiple residues (not in order): • CT1: Ala, Phe •...

QUESTION 9 Sequence analysis of a membrane protein shows four 20 amino acid long stretches of residues that are predominantly hydrophobic Between each of these stretches of hydrodophobic residues, a stretch of predominantly hydrophilic residues is found. From this observation one can reasonably postulate that: A this is a 4 stranded beta barrel which spans the membrane B.this is a glycoprotein o this protein has 4 alpha helical segments that span the membrane o this protein can be removed from...
A chain GIVEQCCASVCSLYQLENYCN B chain FVNQHLCGSHLVEALYLVCGERGFFYTPKA Shown above is the amino acid sequence of the hormone insulin. This structure was determined by Frederick Sanger and his coworkers. Most of this work is described in a series of articles published in the Biochemical Journal from 1945 to 1955. When Sanger and colleagues began their work in 1945, it was known that insulin was a small protein consisting of two or four polypeptide chains linked by disulfide bonds. Sanger and his coworkers...

Consider a polypeptide consisting of 19 amino acid residues. Its structure is shown below. Lys-Tyr-Gly-Gly-Phe-Leu-Arg-Arg-Ile-Arg-Pro-Lys-Leu-Lys-Trp-Asp-Asn-Gln-Tyr . Draw the fragments that would result if the peptide was treated with trypsin. (No partial credit) . Draw the fragments that would result if the peptide was treated with chymotropsin. (No partial credit) MATCH a term from the list below to each definition. Place the letter of the term in the blank to the left of the definition...
