RPSBLAST alignment for GI: 254780386 and conserved domain: TIGR02971

>gnl|CDD|132016 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. Length = 327

 Score = 40.2 bits (94), Expect = 0.001
 Identities = 45/210 (21%), Positives = 91/210 (43%), Gaps = 36/210 (17%)
