Question
Chapter 22, Problem 43P
Interpretation Introduction
Interpretation:
The potential disadvantage of having many catalytic sites on one long polypeptide chain must be determined.
Concept introduction:
A multienzyme complex is an assemble of enzymes, which are the copies of one enzyme, or a cluster of many different enzymes. Its function is to catalyze one reaction or series of reaction in a given pathway. Fatty acid synthase, pyruvate dehydrogenase, glutamine synthetase, and rubisco are examples of multienzyme complexes.

The allosteric site
1). Draw a representation of an allosteric binding site of an enzyme.
must bind an allosteric modifier that maintains three hydrophobic regions, a polar
charged region and two regions of hydrogen bonding. You choose the order or
organization of the characteristics in the allosteric site - label all regions.
Details
the allosteric site is composed of faces of two separate beta sheets and two
separate alpha helices. You might decide that each beta sheet or each alpha helix
contributes one amino acid R group to the allosteric site or you may decide that one of
the beta sheets or one of the alpha helixes contributes two or more amino acid R groups
to the allosteric organization. Your choice but please show R group structure in the
allosteric site!
