The web-server iProEP was developed to predict promoter for eukaryotes and prokaryotes by using the physicochemical properties of the pseudo quadrinucleotide composition with position-correlation scoring function (PCSF). It was observed by the rigorous cross-validation test on the benchmark dataset that the overall success rate achieved by the new predictor was 93.3%, 93.9%, 95.7%, 95.2% and 93.1% in identifying promoter for H. sapiens, D. melanogaster, C. elegans, B. subtilis and E. coli, respectively. A step-by-step guide is given below.

Step 1. Click on the ‘Predictor’ on the navigation bar, choose a suitable species type for prediction.
Step 2. Type the query DNA sequences in FASTA format into the input box. Click on the “example” button below the input box to see the sample sequence in the FASTA format.
Step 3. Click on the “submit” button to obtain the predicted result.

Note:
(1)For each submission, the number of DNA sequences is limited at 1000;
(2)Each DNA sequence must start with a greater-than symbol (“<”) in the first column. The words right after the “>” symbol in the single initial line are optional and only used for the purpose of identification and description.
(3)The query DNA sequence of H. sapiens, D. melanogaster or C. elegans should be no shorter than 300-bp. The query DNA sequence of B. subtilis or E. coli should be no shorter than 81-bp. The accepted characters are: A, C, G, T. If a query sequence contains any illegal character, the prediction will be stopped.
