Abstract excerpt

The nucleotide sequence of the genes encoding the high affinity, branched-chain amino acid transport systems LIV-I and LS has been determined. Seven genes are present on a 7568-base pair DNA fragment, six of which participate directly in branched-chain amino acid transport. Two periplasmic amino acid-binding proteins are encoded by the livJ (LIV-BP) and livK (LS-BP) genes. These two proteins confer specificity on...
