The world’s first protein database for Machine Learning and AI

Ladies and gentlemen I am incredibly proud and excited to present the very first public product of Peptone, the Database of Structural Propensities of Proteins.

Database of Structural Propensities of Proteins (dSPP) is the world’s first interactive repository of structural and dynamic features of proteins with seamless integration for leading Machine Learning frameworks, Keras and Tensorflow.

dSPP is based on peer-reviewed research from leading academic institutions around the world involved in Nuclear Magnetic Resonance spectroscopy techniques for protein structure and disorder characterization. dSPP data are derived from solution and solid state Nuclear Magnetic Resonance spectroscopy experiments for 7200+ unrelated proteins studied under physiologically-relevant conditions.

dSPP is a unique source of information for Intrinsically Disordered Proteins (IDPs), which are a challenging class of proteins to study. IDPs are implicated in numerous debilitating human pathologies, including Alzheimer’s, Parkinson’s, prion diseases, molecular basis of cancer, HIV, HSV, HVC, ZIKVR, and many others.

Structural interpretation of propensity score for MOAG-4 protein, extracted from dSPP database https://peptone.io/dspp/entry/dSPP27058_0. MOAG-4 is known to enhance the process of protein aggregation in animal brain models, thus accelerating an early onset of Parkinson’s disease.

dSPP data can be readily used by experimentalist to gain exclusive insight into structural stability of secondary structure motifs, as well as high throughput computational techniques, which aim to deliver realistic models of medically relevant proteins.

As opposed to binary (logits) secondary structure assignments available in other protein datasets for experimentalists and the machine learning community, dSPP data report on protein structure and local dynamics at the residue level with atomic resolution, as gauged from continuous structural propensity assignment in a range -1.0 to 1.0.

dSPP user interface overview (https://peptone.io/dspp)

dSPP experimental data were collected at physiologically-relevant conditions, rendering them absolutely unique for structure and disorder prediction methods that aim to tackle protein folding and stability in biologically and medically relevant contexts.

dSPP is equipped with intuitive user interface which offers seamless access to relevant decision data, original literature citations, and uniform rendering of Machine Learning data belonging to protein of interest.

Seamless dSPP integration with Keras and Tensorflow machine learning frameworks is achieved via dspp-keras Python package, available for download and setup in under 60 seconds time. Thus, virtually any person with basic understanding of machine learning can start experimenting with protein structure prediction methodology.

dSPP is the first publicly available product by Peptone with automated 14-day updatecycle, made specifically for continuous learning AI applications.
