Abstract
Starch phosphorylase (EC 2.4.1.1) is the key enzyme which catalyzes the reversible conversion of
starch and inorganic phosphate into glucose-1-phosphate (G-1-P) and has been reported in many
higher plants. It can be exploited for industrial purposes for tailoring starch and for the synthesis of
biopolymers which may be useful in food industry and are also of clinical importance. Starch in the
form of insoluble granules accumulates in chloroplasts as the primary product of photosynthesis.
Multiple forms of the enzyme have been reported in different plant tissues which have been
predicted to have different roles in starch metabolism. Here, various biochemical properties have been reviewed. Various techniques for enzyme immobilization have been discussed. Besides,
reports on immobilization of starch phosphorylase from different sources and on different solid
matrices have also been reviewed. Peptide mapping reports of various proteins have also been
assessed in this review.
