Subunit of: glutamate / aspartate ABC transporter

Subunit composition of glutamate / aspartate ABC transporter = [GltI][GltK][GltJ][GltL]
         glutamate / aspartate ABC transporter - periplasmic binding protein = GltI (summary available)
         glutamate / aspartate ABC transporter - membrane subunit = GltK (summary available)
         glutamate / aspartate ABC transporter - membrane subunit = GltJ (summary available)
         glutamate / aspartate ABC transporter - ATP binding subunit = GltL (summary available)

E. coli contains four transporters for the uptake of glutamate (GltIJKL, GltP, GltS, and GadC) and five transporters for the uptake of aspartate (GltIJKL, GltP, DctA, DcuA, and DcuB). GltIJKL accounts for approximately 15% of the total wild-type transport velocity of glutamate, and 25% of the total wild-type transport velocity of aspartate in aerobic growth with succinate and 40 mM NaCl [Schellenberg77].

The GltIJKL glutamate/aspartate transporter is a member of the ATP Binding Cassette (ABC) transporter superfamily [Linton98]. Sequence similarity with known ABC transporter components suggests that GltJK are integral membrane components and GltL is the ABC protein. GltI is the periplasmic-binding component of the GltIJKL glutamate ABC transporter [Linton98]. gltI was shown to be regulated by the FlhDC flagellar transcriptional regulator [Stafford05]. Expression of gltI is greatly reduced when E. coli K-12 strain CS101 is grown in rich medium [Kahane76]. Expression of gltI is also reduced when E. coli W strain D2W is grown with glucose rather than succinate [Willis75].
