|PubMed Abstract||Glycogen phosphorylase isolated from Drosophila melanogaster contains one pyridoxal 5'-phosphate per subunit; the coenzyme is in a hydrophobic environment. Fruit-fly phosphorylase a has lower KM for glucose-1-phosphate and is less sensitive to allosteric inhibitors than the b form of the enzyme. The amino acid composition of Drosophila phosphorylase differs from that of rabbit skeletal muscle phosphorylase. These two enzymes give distinct one dimensional peptide maps. The distribution of reactive SH-groups is markedly different in the insect and vertebrate phosphorylase. Fruit-fly phosphorylase a is dephosphorylated by either rabbit or Drosophila protein phosphatase-1 at a slower rate than rabbit muscle phosphorylase a.|
