✦ Synopsis

Abstract

The active accumulation of L‐arabinose by arabinose induced cultures of Escherichia coli is mediated by 2 independent transport mechanisms. One, specified by the gene locus araE, is membrane bound and possesses a relatively “low affinity.” The other, specified in part by the genetic locus araF, contains as a functional component the L‐arabinose binding protein and functions with a “high affinity” for the substrate. The L‐arabinose binding protein has been purified, partially characterized, crystallized, and sequenced.

Equilibrium binding of Escherichia coli LexA repressor to the recA operator was studied by the polyacrylamide gel mobility shift assay as a function of solution conditions. In the presence of NsCl at 20"C, there was a significant salt dependence in binding to the recA operator, typical for protein-n

The genes encoding the leucine binding proteins in E coli have been cloned and their DNA sequences have been determined. One of the binding proteins (LIV-BP) binds leucine, isoleucine, valine, threonine, and alanine, whereas the other (LS-BP) binds only the D-and L-isomers of leucine. These proteins
