Purification and characterization of alanine carrier isolated from H-proteins of Bacillus subtilis. 1978

I Kusaka, and K Kanai

Alanine transport carrier was isolated and purified from H-proteins of Bacillus subtilis. The purified carrier preparation was homogeneous in migration on polyacrylamide gels containing urea or sodium dodecyl sulfate. Electrophoresis on polyacrylamide gels containing dodecyl sulfate showed a single band of molecular weight of about 7500. 1 mol alanine was bound/mol carrier protein with a dissociation constant of 0.2 micron. The binding was inhibited by p-chloromercuribenzoate and the inhibition was reversed by dithiothreitol.
