Question
Chapter 10, Problem 8E
Summary Introduction
To explain: The amino acids that are particularly abundant at the entrance of a porin that is specific for phosphate ions.
Concept introduction: Porin is a trans-membrane protein that allows the molecules or ions to pass across the membrane. In general, the size of the central aqueous channel and the residues that form at the trans-membrane will determine the type of substance that is able to pass through it.

9) Below, there is a representation of an SDS-PAGE gel. Assuming the samples in the
MW standard have masses of: 66 kDa, 45 kDa, 36 kDa, 29 kDa, 24 kDa, 20.1 kDa, and
14.2 kDa,
a) Figure 4: indicate where each of the measurements were taken and label as in II.6.
figure 2 above.
b) As in II.7. Table 1 above create Table 2 using the data below. Determine the r.f.
values for the MW standards, plot the relative mobility versus the log of the mass
for the standards, and use the best fit straight line to determine the molecular
weights of the proteins in the whey, peak 1, and peak 2 lanes. (5 pts—this will be
scaled up appropriately if your gel did not develop properly)
