Sugar transport through maltoporin of Escherichia coli: role of the greasy slide.

abstract：:At early stages of sporulation, the spoIIA locus is transcribed as a tricistronic (1.7-kb) operon, coding for sigma F and for two proteins that modulate the activity of sigma F. The locus is transcribed as a longer (2.9-kb) transcript at the late stages of sporulation. We show here that the longer transcript contains ...
