Figure 3 Sequences of pig brain -
and -tubulin28
used in the model (in the absence of tubulin sequences from cow
we have used its closest known relative). Secondary structure
elements are indicated and labelled as for Fig. 4. The tubulin
preparations used in our experiments contained a mixture of
isotypes. Most of the differences between isotypes are located
at the extreme C terminus, which is not visible in our density.
In most of the other positions of isotype differences, we
arbitrarily chose the residue most similar to the other monomer.
