Abstract
β-Phenethyl alcohol (PEA) stimulated the inductive formation of inulin fructotransferase (IFT) in Arthrobacter ureafaciens at the transitional phase between the lag and exponential phases of cell growth. The stimulation by PEA was optimal at a concentration of 8.3 × 10−3m. The formation of IFT was repressed by addition of actinomycin D, rifampicin and d-glucose in both the extracellular and cell-bound fractions. Cerulenin, procaine and tunicamycin inhibited the formation of IFT in the extracellular fraction. PEA overcame the repression by rifampicin, d-glucose and tunicamycin of IFT formation. On the basis of these results, it may be suggested that PEA acts directly or indirectly at the level of transcription process and in the glycosylation of protein(s) which may affect the IFT formation.
