Literature summary extracted from

  • Oliver, S.N.; Tiessen, A.; Fernie, A.R.; Geigenberger, P.
    Decreased expression of plastidial adenylate kinase in potato tubers results in an enhanced rate of respiration and a stimulation of starch synthesis that is attributable to post-translational redox-activation of ADP-glucose pyrophosphorylase (2008), J. Exp. Bot., 59, 315-325.

Protein Variants

EC Number Protein Variants Comment Organism
2.7.4.3 additional information transgenic plants containing a construct with an antisense fragment of the plastidial adenylate kinase gene. Decreased expression in growing tubers leads to increased rates of respiratory oxygen consumption and increased carbon fluxes into starch. Increased rates of starch synthesis are accompanied by post-translational redox-activation of ADP-glucose diphosphorylase, while there are no substantial changes in metabolic intermediates or sugar levels Solanum tuberosum
