Biotin uptake by E. coli K12 has been reinvestigated. The vitamin uptake is an active process depending on energy and inhibited by uncouplers. The kinetic parameters (Km = 0.27 μM, Vmax = 6.8 pmol/min/mg dry cells) are close to those previously determined for a biotin-dependent strain E. coli C162 (Piffeteau, A., et. al, 1982). By use of biotin p-nitrophenyl ester, an affinity label of the biotin transport system, it was shown, under conditions of steady state, that the efflux of biotin is not energy dependent and is mainly mediated by a diffusion mechanism. Reexamination of the regulation of the biotin transport by biotin, revealed that only 50% of the biotin uptake system is under control by the vitamin.
