Escherichia coli K-12 substr. MG1655 Polypeptide: YdhP



Gene: ydhP Accession Numbers: G6893 (EcoCyc), b1657, ECK1653

Regulation Summary Diagram: ?

Summary:
The YdhP protein is an uncharacterised member of the major facilitator superfamily (MFS) of transporters [Pao98]. Based on sequence similarity, it may function as a proton-driven drug or sugar efflux system. The ydhP gene probably constitutes a monocistronic operon.

Locations: inner membrane

Map Position: [1,734,145 <- 1,735,314] (37.38 centisomes)
Length: 1170 bp / 389 aa

Molecular Weight of Polypeptide: 40.064 kD (from nucleotide sequence)
