Where
are amino acids closest together? Close pairs probably have positive
and negative charges that attract.
Where
is the inside (probably hydrophobic) and where is the outside
(probably hydrophilic) of this protein? If you have trouble with
this part, go through "What are amino acids anyway?"
There is a long channel with the
binding site inside. See http://www.mbp.duke.edu/mbp/geom/atlas/lyz/gif/lyz_site.gif
How
many disulfide bonds are there? What amino acid seems to be capable
of making them?
What
do those bonds do for the structure of the protein?
Can
you imagine this in 3-D?
