  • Title: Identification of the glycosyl transferase required for synthesis of the principal glycolipid characteristic of heterocysts of Anabaena sp. strain PCC 7120.
    Author: Awai K, Wolk CP.
    Journal: FEMS Microbiol Lett; 2007 Jan; 266(1):98-102. PubMed ID: 17233720.
    Abstract:
    Nitrogenase is oxygen-labile. Cyanobacterial heterocysts can fix N(2) in an oxic milieu because their interior is micro-oxic, for which the glycolipid layer of the heterocyst envelope is required. ORF all5341 of the Anabaena sp. genome predicts a glycosyl transferase. An insertional mutant of all5341 synthesized only a nonglycosylated form of heterocyst envelope glycolipid, and lacked a glycolipid layer. All5341 appears to be the transferase required to glycosylate the glycolipid aglycone.
