...This certainly represents the data well, but one could equally well have cho-
sen to take the point of view of the substrates instead of the proteins, as
follows:...
<Substrate id="Sub89032">
<Protein id="Mas375">
<BindingStrength>5.67</BindingStrength>
<Concentration unit="nm">43</Concentration>
</Protein>
<Protein id="Mtr245">
<BindingStrength>0.65</BindingStrength>
<Concentration unit="um">0.53</Concentration>
</Protein>
...
</Substrate>
<Substrate id="Sub8933">
<Protein id="Mas375">
<BindingStrength>4.37</BindingStrength>
<Concentration unit="nm">75</Concentration>

<Protein id="Mtr245">
