Terminators of Transcription with RNA Polymerase fromEscherichia coli:What They Look Like and How to Find Them

Abstract
We present here a compilation of prokaryotic transcription terminator sequences (ref. 1–152). The compilation includes 49 independent terminators, 52 speculated independent terminators, 27 sites shown to function in vivo, and some 20 proven or speculated rho-dependent terminators. In addition to the well-known features of independent terminators (dyad symmetry and T-run), two consensus sequences are found: CGGG(C/G) upstream and TCTG downstream of the termination point. A subset of the collection of sequences has been used to construct a computer algorithm to locate independent terminators by sequence analysis.
