Escherichia coli K-12 substr. MG1655 Polypeptide: YjeM APC transporter



Gene: yjeM Accession Numbers: EG12475 (EcoCyc), b4156, ECK4152

Regulation Summary Diagram: ?

Summary:
YjeM is an uncharacterized member of the APC superfamily of amino acid transporters [Jack00]. Membrane topology predictions using experimentally determined C terminus locations indicate that YjeM has 12 transmembrane helices and the C-terminus is located in the cytoplasm [Rapp04].

Locations: inner membrane

Map Position: [4,381,862 -> 4,383,364] (94.44 centisomes)
Length: 1503 bp / 500 aa

Molecular Weight of Polypeptide: 54.725 kD (from nucleotide sequence)
