Starch Phosphorylase: Biochemical and Biotechnological New Perspectives | Chapter 3 | Theory and Applications of Microbiology and Biotechnology Vol. 3
A dynamic mediatory role between starch synthesis and
degradation has been ascribed to starch phosphorylase. However, plant starch
phosphorylase is largely considered to be involved in phosphorolytic
degradation of starch. It reversibly catalyzes the transfer of glucosyl units
from glucose-1-phosphate to the non-reducing end of glucan chain with the
release of inorganic phosphate. It is widely distributed in plant kingdom.
Enzyme multiplicity is also common in starch phosphorylase and different
multiple forms have been predicted to have different roles in starch
metabolism. Here, various biochemical properties have been reviewed. Its
regulation by aromatic amino acids has also been discussed. Importance of
plastidial and cytoplasmic starch phosphorylase has also been discussed.
Various biotechnological aspects have been discussed. Its exploitation in
production of glucose-1-phosphate, a cytostatic compound has been discussed in
the present review.
