So
how exactly do you determine the structure and the functionality
of something
that
isvisibly
impossible to see? The preferred technique for solving enzymes
is called
crystallography.
Using this, along with a few other analysis methods (see methods),
“Group
15 the Great” will set out with a plan of attack.
First, determine the general structure of the two villains: code names Cocaine
and
Heroin. Once
the molecular structure of these molecules is determined, they
should
further be examined
for anything in their structure which would help an
enzyme “grab
hold” or bond to them.
In most cases, this is the oxygen in the
molecule. Oxygen
loves electrons and generally
creates a negative charge on
one
end of the molecule which can attract other molecules to it.

Meanwhile, the enzyme itself must be solved. In other words, the
structure of the
actual
binding site must be determined to see how the two molecules of
cocaine
and
heroin are able to fit in. Once
the general shape of the enzyme’s
active
site is determined, further
analysis of the amino acids making up
the
proteins in
the active site need to be conducted. Specifically,
the
oxygen groups on
the cocaine and heroin molecules must match
up
with specific amino
acids in the active site in order to attract the molecules
to
these sites. Also, flexibility in the amino acid sequence of
the
protein should be determined- as flexibility in an active site
is
crucial for an enzyme to act promiscuously.

If
all these characteristics could be identified, then
the mystery of the function of
MOLECULAR
MAN (hCE1
Promiscuous enzyme) will be solved!
