Escherichia coli K-12 substr. MG1655 Polypeptide: conserved inner membrane protein



Gene: yqhA Accession Numbers: G7559 (EcoCyc), b3002, ECK2996

Regulation Summary Diagram: ?

Summary:
YqhA is predicted to be an integral membrane protein [vanHam97].

YqhA has similarity to an episomally-encoded protein from Buchnera aphidicola, which exists intracellularly in a symbiotic relationship with multiple species of aphid [vanHam97].

Locations: inner membrane

Map Position: [3,146,999 <- 3,147,493] (67.83 centisomes)
Length: 495 bp / 164 aa

Molecular Weight of Polypeptide: 18.641 kD (from nucleotide sequence)
