Abstract: Polyamines are primordial, small organic polycations present in almost all cells, but their roles in bacteria are poorly understood. sym‐Homospermidine is the dominant polyamine in the filamentous, N2‐fixing, heterocyst‐forming cyanobacterium Anabaena sp. PCC 7120. Synthesis… read more here.

Abstract: Since nitrogenase is extremely vulnerable to oxygen, aerobic or micro-aerobic nitrogen-fixing organisms need to create anaerobic microenvironments in the cells for diazotrophic growth, which would be one of the major barriers to express active nitrogenase… read more here.
