Abstract:
Alpha glucan phosphorylase plays a very
significant role in glycolysis. The inhibition and
activation of this enzyme have significant effect on
the rate of glycolysis. The rate of glycolysis is
also determined by the interconversion between the
active 3 and inactive Q forms of phosphorylase by
two specific enzymes called phosphorylase phosphatase
and phosphorylase kinase. The allosteric properties
and interconversion mechanism reported for
well—studied animal muscle phosphorylases do not
fall under a general pattern. Studies using
purified phosphorylase from marine sources are scanty.
Detailed studies using specialised tissues from more
marine animals are necessary to find the factors that
control the properties and activities of the enzyme.
This thesis is an attempt in this direction. The
thesis deals with a detailed study of the control of
the phosphorylase by both allosterism and
interconversion between the g and b forms from four
different aquatic animals of different habitat. Phosphorylase frm the four different animal muscles were purified either partially or completely and the kinetic and control properties were studied.
