ABC transporter is a large family mainly comprising high-affinity branched-chain amino acid transporter proteins such as Escherichia coli LivH P08340 and LivM P22729 both of which are from the LIV-I transport system [ 1 ]. Also found with in this family are proteins from the galactose, ribose, xylose, arabinose and fructose transport system permeases [ 2 , 3 , 4 , 5 ], as well as nucleoside transporters [ 6 , 6 ].
