Anabaena sp. strain PCC 7120 gene devH is required for synthesis of the heterocyst glycolipid layer.

Journal of bacteriology - 1 Apr 2005

Abstract excerpt

In response to deprivation for fixed nitrogen, the filamentous cyanobacterium Anabaena sp. strain PCC 7120 provides a microoxic intracellular environment for nitrogen fixation through the differentiation of semiregularly spaced vegetative cells into specialized cells called heterocysts. The devH gene is induced during heterocyst development and encodes a product with characteristics of a trans-acting regulatory...
