Consider the following simplified schematic of a transmembrane beta-sheet forming a transport protein, shown in cross section, with each numbered R group indicating the side chain of a specific amino acid residue: R1 R2 R3 R4 R5 polypeptide backbone central aqueous pore Which of the following amino acids could be possible candidates for residue 3? Select ALL that apply. serine lysine valine isoleucine glutamate

Single-pass transmembrane proteins span a membrane with a single ̑̑α-helix that has characteristic chemical properties in the region of the bilayer. Which of the three 20-amino-acid sequences listed below is the most likely candidate for such a transmembrane segment? Explain the reasons for your choice. A. ITYIYFGSMAGVIGTQLLIS B. ITPIYFGPMAGVIGTPLLIS C. ITAIYFGFMAGVIGTWLLIS
