The EMBL Data Library was the first internationally supported central resource for nucleic acid sequence data. Working in close collaboration with its American counterpart, GenBank (1), the library prepares and makes available to the scientific community a comprehensive collection of the published nucleic acid sequences. This paper describes briefly the contents of the database, how it is available, and possible future enhancements of Data Library services.
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 are found: CGGG(C/G) upstream and TCTG downstream of the termination point. A subset of the collection of sequence has been used to construct a computer algorithm to locate independent terminators by sequence analysis.
