Abstract


The YPR184w gene encodes a 1536-amino acid protein that is 34-39% identical to the mammal, Drosophila melanogaster and Caenorhabditis elegans glycogen debranching enzyme. The N-terminal part of the protein possesses the four conserved sequences of the alpha-amylase superfamily, while the C-terminal part displays 50% similarity with the C-terminal of other eukaryotic glycogen debranching enzymes. Reliable measurement of alpha-1,4-glucanotransferase and alpha-1, 6-glucosidase activity of the yeast debranching enzyme was determined in strains overexpressing YPR184w. The alpha-1, 4-glucanotransferase activity of a partially purified preparation of debranching enzyme preferentially transferred maltosyl units than maltotriosyl. Deletion of YPR184w prevents glycogen degradation, whereas overexpression had no effect on the rate of glycogen breakdown. In response to stress and growth conditions, the transcriptional control of YPR184w gene, renamed GDB1 (for Glycogen DeBranching gene), is strictly identical to that of other genes involved in glycogen metabolism.
