Abstract Near-full-length cDNA clones to the small and large subunit of the heterotetrameric potato tuber ADP-glucose pyrophosphorylase have been isolated and characterized. The missing amino terminal sequence of the small subunit has also been elucidated from its corresponding genomic clone. Primary sequence comparisons revealed that each potato subunit had less identity to each other than to their homologous subunit from other plants. It also appeared that the smaller subunit is more conserved among the different plants and the larger subunit more divergent. Amino acid comparisons of both potato tuber sequences to theEscherichia coli ADP-glucose pyrophosphorylase sequence revealed conserved regions important for both catalytic and allosteric function of the bacterial enzyme.
