Reaction:		(1) L-cystine(out) + Atp + H2O = L-cystine(in) + adp + phosphate + H(+). (2) D-cystine(out) + Atp + H2O = D-cystine(in) + adp + phosphate + H(+).
		L-cystine(out) + ATP + H2O = L-cystine(in) + ADP + phosphate + H(+) D-cystine(out) + ATP + H2O = D-cystine(in) + ADP + phosphate + H(+) Molecule diagrams generated from .mol files obtained from the KEGG ftp site.
Other name(s):		cystine Abc transporter. cystine transporting ATPase.
Comments:		ABC-type (ATP-binding cassette-type) transporter, characterized by the presence of two similar ATP-binding domains/proteins and two integral membrane domains/proteins. A bacterial enzyme that interacts with an extracytoplasmic substrate binding protein and mediates the high affinity import of trace cystine. The enzyme from Escherichia coli K-12 can import both isomers of cystine and a variety of related molecules including djenkolate, lanthionine, diaminopimelate and homocystine.
