Characterization of pFR18, a small cryptic plasmid from Leuconostoc mesenteroides ssp. mesenteroides FR52, and its use as a food grade vector.

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 ...
