You have identified a novel protein that associates with the plasma membrane. you do not know whether this protein is a peripheral or a transmembrane protein. you therefore analyze the primary amino acid sequence (listed in the three letter code) for the presence of a transmembrane domain. met - asp - leu - lys - ile - pro - gly - val - glu - arg - met - phe - leu - ile - ser - lys - gly - thr - asp - tyr - his - asn - gln - val - asp - met - val - gly - pro - asp - glu - gly - ala - ala - ala - val - met - arg - trp - lys - cys - met - phe - ile - val - val - val - thr - val - glu - glu - gly - asp - met - val - ala - ile - ile - val - leu - pro - lys - arg - trp - tyr - phe - ala - gln - tyr - ala - val - leu - ile - leu - met - ala - trp - leu - val - phe - val - ile - leu - ala - arg - lys - his - ala - val - ile - leu - trp - tyr - ala - gly - gln - gly - asn - arg - his - cys - lys - met - ser - pro - gly - ala - met - asp - ser - glu - ile - leu - met - phe - trp - gly - lys - cys - met - leu - trp - phe - arg - met - leu how many potential transmembrane domains can you identify in this protein?
