摘要

Nigericin, an ionophorous antibiotic, is converted to epi nigericin by the ciliate Tetrahymena pyriformis. Bioconversion occurs in the presence of intact cells but not with broken cells (sonicated ciliates). However, broken cells obtained from intact ciliates pretreated with 1 mg/l of nigericin, before sonication, converted nigericin to epinigericin. Non-impairment after adding actinomycin D and cycloheximide to the ciliate culture suggests that the induction mechanism involves no mRNA synthesis, nor any de novo synthesis of protein. Cell fractionation of Tetrahymena demonstrates that the cytosolic compartment is implicated in this bioconversion. [References: 26]
