The Escherichia coli metD locus encodes an ABC transporter which includes Abc (MetN), YaeE (MetI), and YaeC (MetQ).

ABSTRACT: We report that the genes abc, yaeC, and yaeE comprise metD, an Escherichia coli locus encoding a DL-methionine uptake system. MetD is an ABC transporter with Abc the ATPase, YaeE the permease, and YaeC the likely substrate binding protein. Expression of these genes is regulated by L-methionine and MetJ, a common repressor of the methionine regulon. We propose to rename abc, yaeE, and yaeC as metN, metI, and metQ, respectively.
