May 17th Workshop 2
Background for homework…Background for homework…Cytochrome c is a peripheral membrane
protein that “floats” on the inner mitochondrial membrane, shuttling electrons from Complex III to Complex IV of the Electron Transport Chain.

Using the amino acid single letter code, write the primary structure of the Cytochrome c found in your organism.
Residue Number Mole%A = Ala 6 5.714 C = Cys 2 1.905 D = Asp 3 2.857 E = Glu 8 7.619 F = Phe 3 2.857 G = Gly 13 12.381 H = His 3 2.857 I = Ile 8 7.619 K = Lys 18 17.143 L = Leu 6 5.714 M = Met 4 3.810 N = Asn 5 4.762 P = Pro 4 3.810 Q = Gln 2 1.905 R = Arg 2 1.905 S = Ser 2 1.905 T = Thr 7 6.667 V = Val 3 2.857 W = Trp 1 0.952 Y = Tyr 5 4.762
Property Residues Number Mole%Non-polar (A+C+F+G+I+L+M+P+V+W+Y) 55 52.381Polar (D+E+H+K+N+Q+R+S+T) 50 47.619
In humans there are about 52% hydrophobic amino acids in Cytochrome c. How many in your organism???
