Studies were made on the effects of incubation temperature, glycolysis inhibitor and vitamin B_6 analogues on the transport of B_6 into human erythrocytes. The transported amounts of pyridoxine and pyridoxamine into the cells diminished in the low temperature, but pyridoxal did not. Potassium fluoride inhibited the transport of pyridoxine, pyridoxamine and pyridoxal phosphate into the cells, but did not the transport of pyridoxal. Furthermore, pyridoxal phosphate concentrations in the cells after incubation with free forms of B_6 were decreased by the addition of potassium fluoride. Deoxypyridoxine inhibited competitively the transport of pyridoxine and pyridoxamine into the cells, but did not the transport of pyridoxal and pyridoxal phosphate. Pyridoxal phosphate concentrations in the cells after incubation with free forms of B_6 were decreased by the addition of deoxypyridoxine. Deoxypyridoxine phosphate did not inhibited the transport of various forms of B_6.
