<P><B>Significance</B></P><P>Identification of enzyme commission (EC) numbers is essential for accurately understanding enzyme functions. Although several EC number prediction tools are available, they have room for further improvement with respect to computation time, precision, coverage, and the total size of the files needed for EC number prediction. Here, we present DeepEC, a deep learning-based computational framework that predicts EC numbers with high precision in a high-throughput manner. DeepEC shows much improved prediction performance when compared with the 5 representative EC number prediction tools that are currently available. DeepEC will be useful in studying enzyme functions by implementing them independently or as part of a third-party software program.</P><P>High-quality and high-throughput prediction of enzyme commission (EC) numbers is essential for accurate understanding of enzyme functions, which have many implications in pathologies and industrial biotechnology. Several EC number prediction tools are currently available, but their prediction performance needs to be further improved to precisely and efficiently process an ever-increasing volume of protein sequence data. Here, we report DeepEC, a deep learning-based computational framework that predicts EC numbers for protein sequences with high precision and in a high-throughput manner. DeepEC takes a protein sequence as input and predicts EC numbers as output. DeepEC uses 3 convolutional neural networks (CNNs) as a major engine for the prediction of EC numbers, and also implements homology analysis for EC numbers that cannot be classified by the CNNs. Comparative analyses against 5 representative EC number prediction tools show that DeepEC allows the most precise prediction of EC numbers, and is the fastest and the lightest in terms of the disk space required. Furthermore, DeepEC is the most sensitive in detecting the effects of mutated domains/binding site residues of protein sequences. DeepEC can be used as an independent tool, and also as a third-party software component in combination with other computational platforms that examine metabolic reactions.</P>
