Macke T, Ecker D, Gutell R, Gautheret D, Case DA and Sampath R.(2001) Prediction of rho-independent transcriptional terminators (1994) Fast Folding and comparison of RNA Hofacker IL, Fontana W, Stadler PF, Bonhoeffer LS, Tacker M and Schuster P.(2001) Direct RNA Motif Definition and Identificationįrom Multiple Sequence Alignments using Secondary Structure Profiles. Free energy of stem-loop region (kcal/mol).Indicate the spacer element, between the stem-loop and T-rich region. Lowercase letters in RNAmotif predictions Sequence (parenthesis or colors indicate terminator stem).5' end position of predicted transcription terminator (for terminators on minus strand, position is given in plus strand coordinates, end of terminator first). Results are displayed in a single page, with the following information given for each predicted terminator: Inverse U and T: keeps U/T as in input, or reverse.Colored secondary structures: transforms the parenthesis in colored secondary.Search strand: perform analysis on forward, reverse, or both strands.Input sequences to be analyzed in the text area or upload from a local file.ĭNA or RNA sequences are accepted. This free energy value may be used as a confidence value for predicted terminators. Terminator stem-loop structure using RNAfold (Hofacker et al. To provide a uniform scoring scheme for Erpin and RNAmotif hits, we compute the free energy of the predicted RNAmotif matches are scored using the sequence contents of the T-rich region and stability of the stem loop regionĪnd an emprirical score cutoff is defined to accept or reject matches. Of a 4-18 bp helix, a 0-2 nt spacer and a 12 nt T-rich region. However it can be applied to find terminators from any species. 2001) uses a descriptor developed by Lesnik et al. It builds a lod-score profile from this alignment and seeks high scoring instances of the Erpin (Gautheret & Lambert, 2001) is givenĪ structure-annotated alignment of 1200 terminator sequences from Bacillus subtilis and Escherichia coliĪs a training set.The search procedure uses two complementary programs, Erpin and RNAmotif. Inverse U and T – select whether or not you want to keep Us (or Ts) as in input sequence or change them to Ts (or Us):ĪRNold finds rho-independent terminators in nucleic acid sequences. Paste one or more nucleic acid sequences in FASTA format (max 5Mb): ( principles, help) Easy identification of Rho–independent transcription terminators
