Inactivation of a heterocyst-specific invertase indicates a principal role of sucrose catabolism in heterocysts of Anabaena sp.

Journal of bacteriology - 1 Oct 2010

López-Igual Rocío, Flores Enrique, Herrero Antonia

Abstract excerpt

Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that carries out N(2) fixation in specialized cells called heterocysts, which exchange nutrients and regulators with the filament's vegetative cells that perform the photosynthetic fixation of CO(2). The Anabaena genome carries two genes coding for alkaline/neutral invertases, invA and invB. As shown by Northern analysis, both genes were expressed...
