DE   ABC-type cystine transporter.
AN   cystine ABC transporter.
AN   cystine transporting ATPase.
CA   (1) ATP + H2O + L-cystine(out) = ADP + H(+) + L-cystine(in) + phosphate.
CA   (2) ATP + D-cystine(out) + H2O = ADP + D-cystine(in) + H(+) + phosphate.
CC   -!- ABC-type (ATP-binding cassette-type) transporter, characterized by
CC       the presence of two similar ATP-binding domains/proteins and two
CC       integral membrane domains/proteins.
CC   -!- A bacterial enzyme that interacts with an extracytoplasmic substrate
CC       binding protein and mediates the high affinity import of trace
CC       cystine.
CC   -!- The enzyme from Escherichia coli K-12 can import both isomers of
CC       cystine and a variety of related molecules including djenkolate,
CC       lanthionine, diaminopimelate and homocystine.
