Escherichia coli K-12 substr. MG1655 Protein: YbbA/YbbP ABC transporter

Subunit composition of YbbA/YbbP ABC transporter = [YbbP]2[YbbA]2

Summary:
YbbA and YbbP are uncharacterized members of the ABC superfamily of transporters [Saurin99]. YbbA is the putative ATP binding component. YbbP may be the membrane component. Based on sequence similarity, these proteins may work together as part of an ATP dependent metabolite uptake system. The genes ybbA, and ybbP are probably located within a single operon.
