Protein
Bifunctional polyhydroxybutyrate synthase / ABC transporter periplasmic binding protein
Organism
Escherichia coli (strain K12)
Function
Catalyzes the formation of short polymers of R-3-hydroxybutyrate (cPHB) (PubMed:18640095). Involved in natural transformation (PubMed:26826386). Probably part of the ABC transporter complex YdcSTUV. During natural transformation, may bind dsDNA and convey it to the inner membrane channel formed by YdcV (Probable).
Similarity
Belongs to the bacterial solute-binding protein PotD/PotF family.
