CnnPOGTP

CnnPOGTP predicts optimal growth temperatures (OGTs) of prokaryotes from genomic sequences using convolutional neural networks trained on genomic k-mer distribution patterns.

Key Features:

• k-mer Distribution-Based Prediction: Utilizes genomic k-mer distribution patterns extracted from DNA sequences to infer optimal growth temperatures of prokaryotic organisms.
• Convolutional Neural Network Model: Applies deep learning with convolutional neural networks to learn sequence-derived features associated with microbial thermal adaptation.
• Annotation-Free Genome Analysis: Predicts OGTs directly from genome sequences without requiring gene annotation or additional biological metadata.

Scientific Applications:

• Microbial Ecology: Supports inference of thermal preferences of prokaryotes from genomic data, aiding ecological characterization of microorganisms.
• Metagenomic Analysis: Enables estimation of growth temperature characteristics for organisms reconstructed through metagenomic binning.
• Biotechnology and Cultivation Studies: Assists identification of suitable temperature conditions for isolating and cultivating uncultured prokaryotic species.

Methodology:

CnnPOGTP analyzes genomic k-mer distributions derived from prokaryotic genome sequences and applies a convolutional neural network trained on genomes with known optimal growth temperatures to predict OGT values.
