Protein
Probable ABC transporter phosphite binding protein PhnD1
Organism
Prochlorococcus marinus (strain MIT 9301)
Function
Probably part of the ABC transporter complex PhnD1C1E1. Binds strongly to inorganic phosphite and with very weak affinities to methylphosphonate (MPn) and phosphate.
Similarity
Belongs to the phosphate/phosphite/phosphonate binding protein family.
