• PhagePromoter- is a tool for locating promoters in phage genomes, using machine learning methods. This is the first online tool for predicting promoters that uses phage promoter data and the first to identify both host and phage promoters with different motifs. It is part of Galaxy.(Reference: Sampaio M et al. (2019) Bioinformatics.
• Therefore, PhagePromoter, a software tool that allows identifying phage promoters, using machine-learning models trained with phage sequences, was developed. This tool searches the whole genome for promoters and it can identify both types of promoters found in phage genomes and different motifs of each promoter type. 2 Materials and methods 2.1.

In a nutshell, HOMER contains two tools, findMotifs.pl and findMotifsGenome.pl, that manage all the steps for discovering motifs in promoter and genomic regions, respectively. These scripts attempt to make it easy for the user to analyze a list of genes or genomic positions for enriched motifs.

iPro70-PseZNC - is a tool for identifying σ70 promoters with novel pseudo nucleotide composition (Reference: Lai H-Y et al. (2019) Mol Ther Nucleic Acids. 17: 337-346). I would recommend using <100 nt upstream from the start codon.

iPro54-PseKNC - is a sequence-based predictor for identifying sigma-54 promoters in prokaryote with pseudo k-tuple nucleotide composition. (Reference: Lin H et al. (2014) Nucleic Acids Res 42(21): 12961-12972).
Promoter Prediction by Neural Network (Martin Reese, Lawrence Berkeley Laboratory, CA, U.S.A.) - applicable to eukaryotes and prokarotes (Reference: Reese MG, 2001. Comput Chem 26: 51-56). Dated and prokaryote results must be viewed skeptically.

Virtual Footprint - offers two types of analyses (a) Regulon Analysis - analysis of a whole prokaryotic genome with one regulator pattern and (b) Promoter analysis - Analysis of a promoter region with several regulator patterns (Reference: R. Münch et al. 2005. Bioinformatics 2005 21: 4187-4189).

PePPER(University of Groningen, The Netherlands) is a webserver for prediction of prokaryote promoter elements and regulons (Reference: de Yong, A. et al. 2012. BMC Genomics 13:299).

DOOR3 - Database of prOkaryotic OpeR Download dragon mania legends pc. ons - offers high-performance web service for online operon prediction on user-provided genomic sequences; and, an intuitive genome browser to support visualization of user-selected data. Plus a huge database of transcriptional units. (Reference: X. Mao et al. 2014. Nucleic Acids Res. 42(Database issue): D654-9).

PATLOC (Pattern Locator) (Institute of Bioinformatics, University of Georgia, U.S.A.) - is a new tool for finding sequence patterns in long DNA sequences. For this web-based service, a restricted version of Pattern Locator is used, which estimates the time needed for completion of the search and stops if the estimated CPU time exceeds a certain limit (currently 90 seconds). The CPU time limit was introduced in order to protect the web server from overloading due to requests involving too complex sequence patterns. If you want to search for Sigma-70 (RpoD)-like promoters the pattern syntax for your search is: <>{TTGACA(N)[15:18]TATAAT}[4]. N.B. the [4] allows for 4 mismatches - I recommend a maximum of two. If you only want one strand screened omit the <> at the start. You can restrict the search to intergenic regions (but this will eliminate also matches that partially overlap with genes or use the .patvic.txt output file to find where they are (Jan Mrázek, personal communication).

SeqTU (RNA-seq Based Transcription Unit Finder for Prokaryotes) - is a recently developed machine-learning method to accurately identify TUs from RNA-seq data, based on two features of the assembled RNA reads: the continuity and stability of RNA-seq coverage across a genomic region. While good performance was achieved by the method on Escherichia coli and Clostridium thermocellum, substantial work is needed to make the program generally applicable to all bacteria, knowing that the program requires organism specific information.(Reference: Chen X et al. (2017) Sci Rep. 7: 43925).

B. Eukaryotic

Not being a eukaryotic molecular biologist I cannot comment on utility and accuracy of the following promoter- prediction programs.

FindM(Find Motifs around Functional Sites) - choose Promoter Motifs from Motif Library

C. Transcriptional terminators - these only apply to rho-independent terminators; for rho-dependent termiantor sites see

Transcription Terminator Prediction (Anne de Jong, University of Groningem, The Netherlands) - is part of the excellent Genome2D webserver for Analysis and Visualization of Bacterial Genomes and Transcriptomes

WebGeSTer - Genome Scanner for Terminators - my favourite terminator search program is finally web enabled. Please note that if you want to analyze data from a *.gbk file you need to use their conversion program 'GenBank2GeSTer' first.A complete description of each terminator including a diagram is produced by this program. This site linked to an extensive database of transcriptional terminators in bacterial genome (WebGeSTer DB) (Reference: Mitra A. et al. 2011. Nucl. Acids Res.39(Database issue):D129-35).

ARNold - finds rho-independent terminators in nucleic acid sequences using two complementary programs, Erpin and RNAmotif. The program colors the terminator stem and loop (References: Gautheret D, Lambert A. 2001. J Mol Biol. 313:1003–11 & Macke T. et al. 2001. Nucleic Acids Res. 29:4724–4735 ).

FindTerm(Softberry Inc.) - can also be used for mapping rho-independent terminators. You might consider using the advanced feature options and minimally increase the default energy threshold to -12.0. Please note that the online version of this program will only find one terminator at a time. If you are dealing with a long sequence, once you have located a terminator, delete it from the DNA sequence and resubmit.
RibEx: Riboswitch Explorer - scans <40kb DNA for potential genes (which are linked to BLASTP) and several hundred regulatory elements, including riboswitches. If you click on the 'search for attenuators' it finds terminators and antiterminators. (Reference: C. Abreu-Goodger & E. Merino. 2005. Nucl. Acids Res. 33: W690-W692).

iTerm-PseKNC - is a webserver for the identification of bacterial transcriptional terminators based on machine learning method. In the predictor, 5-tuple nucletide frequency and physicochemical property were extracted to formulate samples. The binomial distribution technique was proposed to rank 1024 5-tuple nucleotides. Then the incremental feature selection (IFS) was used to determine the optimal features which could produce the maximum accuracy. The support vector machine (SVM) was utilized to perform prediction. Five-fold cross-validated results showed that 86.07% terminators and 99.46% non-terminators can be correctly recognized, respectively. (Reference: Lai H-Y et al. (2019) Mol Ther Nucleic Acids. 17: 337-346).
