Escherichia coli is known to excrete putrescine rapidly after a sudden elevation in the osmolarity of the medium. We report here that mutants defective in the transport of potassium ions display a greatly diminished rate of [(14)C]putrescine excretion.
众所周知,在培养基渗透压突然升高后,大肠杆菌会迅速分泌腐胺。我们在此报告,钾离子转运存在缺陷的突变体分泌[(14)C]腐胺的速率大幅降低。
