Escherichia coli K-12 substr. MG1655 Polypeptide: periplasmic cystine-binding protein; member of extracellular bacterial solute-binding protein family III



Gene: fliY Accession Numbers: G7039 (EcoCyc), b1920, ECK1919

Synonyms: yzzR, ssi7

Regulation Summary Diagram: ?

Summary:
FliY is a periplasmic [Mytelka96] cystine-binding protein [Butler93]. FliY is a family 3-type extracellular bacterial solute-binding protein [Mytelka96]. FliY is suggested to participate in transport of amino acid-like compounds and/or in regulation of class III transcription [Mytelka96]. The corresponding gene in Salmonella typhimurium is transcribed from both flagellar and non-flagellar promoters, suggesting that fliY may not be a flagellar gene [Ikebe99a].

The protein is produced as a precursor with a cytoplasmic export signal, and the precursor is processed to yield a mature form of 27 kDa [Mytelka96].

Overproduction does not affect motility [Mytelka96]. A fliZ fliY double mutant shows a partial defect in motility [Mytelka96], which is suggested to be due to the fliZ mutation [Ikebe99a].

FliY has similarity to E. coli PheC [Mytelka96], to the L-cystine uptake protein of Lactobacillus fermentum BR11, BspA, [Turner99a], and to the Salmonella typhimurium FliY protein [Ikebe99a].

FliY, YecS and YecC may function as a cystine transport system [Kertesz01].

Regulation has been described [Mytelka96, Kirkpatrick01, Quadroni96, Ikebe99a]. Protein abundance is increased by acetate supplementation of the media [Kirkpatrick01] or by sulfate starvation [Quadroni96]. The corresponding gene in Salmonella typhimurium is transcribed from both the flagellar promoter upstream of the fliA gene and from a non-flagellar promoter upstream of the fliY gene [Ikebe99a].

Ssi7: "sulfate starvation-induced" [Quadroni96].
