TIGR02971: heterocyst_DevB 
ABC exporter membrane fusion protein, DevB family
Members of this protein family are found mostly in the Cyanobacteria, but also in the Planctomycetes. DevB from Anabaena sp. strain PCC 7120 is partially characterized as a membrane fusion protein of the DevBCA ABC exporter, probably a glycolipid exporter, required for heterocyst formation. Most Cyanobacteria have one member only, but Nostoc sp. PCC 7120 has seven members.
