Promoter Strength Predictor

Welcome to our utility for promoter strength prediction. See how the Application Works.


How Does Our Application Work ?

This website serves as a Python based machine learning platform to predict the strength of σ70 core promoters in Escherichia coli in a manner that subverts the need for tedious experiments and is cost effective.

Here the user will have to enter the -10 and -35 regions in the input boxes and the platform will return the strength of the input promoter relative to the strength of the strongest Anderson promoter. The dynamic model is optinal and the user can click "Predict" once the Sequences are entered.

The advent of genetic engineering over the last few decades has opened up new avenues for biologists. One of them has been expressing proteins in organisms of their choice and altering the level of protein expression. Escherichia coli has been the lab workhorse and ideal model organism for many years, given the ease with which it can be grown in a lab, its extensive characterization of a variety of strains and high level of safety. The sigma 70 promoters in the organism are ubiquitously used by genetic engineers to initiate transcription. Yet, their characterization in a lab remains to be a time consuming and expensive process.

Who We Are ?

Ashok Palaniappan

Ashok Palaniappan is very interested in applying computational thinking to solve difficult biological problems. He has demonstrated expertise in the development of computational methods, notably the use of Fourier spectrum analysis to detect periodicity in evolutionary conservation of protein secondary structure.  

He has shown ability to develop novel approaches for difficult biological problems, notably the identification of stage-specific biomarkers in colon and liver cancer tumorigenesis, progression and metastasis. Ashok obtained his PhD from the University of Illinois at Urbana-Champaign, USA (2005). He is Senior Assistant Professor in the School of Chemical and Biotechnology, Sastra University, Thanjavur 613401.

Ramit B

Ramit is an undergraduate student in his final year studying Biotechnology Engineering at Sri Venkateswara College of Engineering, Anna University. He is looking to carve out a career in synthetic biology given the exciting possibilities that the field has. He was an integral part of his colleges iGEM team in 2016. He is the team of leader of his college’s 2017 iGEM team.

After learning about the exciting prospects of Machine learning algorithms, he intends to apply them to biological data sets to make meaningful inferences from them or build tools that can save time and money in the lab for Biologists. He believes that a true product of engineering is often one that is born out of a mixture of different fields and that combining the prowess of two burgeoning fields of the 21st century – Synthetic biology and Machine Learning could lead to exciting products and services in the future.
