Abstract
Expression of methionine regulon elements was controlled by the metJ protein gpMetJ. A maxicell system with cloned copies of the metF transcription unit allowed reversible action of gpMetJ. Expression of the metF transcription unit in maxicells was reduced by exogenous vitamin B12 at concentrations of 0.5 nM or greater.
摘要
甲硫氨酸调节子元件的表达受metJ蛋白gpMetJ的控制。带有metF转录单位克隆拷贝的大细胞系统可实现gpMetJ的可逆作用。在大细胞中，当外源维生素B12浓度达到0.5 nM或更高时，metF转录单位的表达会降低。
