Transcription termination and pausing at the his terminator

Template and complex type	No. of observations	Mean pause duration, s*	Pause duration distribution time constant τ, s*
his template
Termination	59	64  ±  11	67  ±  2
Read through	32	16  ±  7	17  ±  1
Control template
Read through	25	16  ±  7	18  ±  1

^*Values (± SE) are based on measurements of the longest pause in the vicinity of the terminator (see Methods).
