Synthetic biology: engineering Escherichia coli to see light.

abstract：:Vitamin A is required for normal growth and development, and retinoic acid (RA) may be the active metabolite in this process. Recent evidence indicates that RA acts through binding to a nuclear receptor which belongs to the steroid/thyroid hormone receptor superfamily. The receptors seem to associate with hormone-resp...
