Escherichia coli K-12 substr. MG1655 Polypeptide: YjhB MFS transporter



Gene: yjhB Accession Numbers: EG12544 (EcoCyc), b4279, ECK4269

Regulation Summary Diagram: ?

Summary:
The YjhB protein is an uncharacterised member of the major facilitator superfamily (MFS) of transporters [Pao98]. Based on sequence similarity, YjhB may function as a proton-driven metabolite uptake system, possibly for sialic acid or related substrates.
