+## About
+
+DEER (Dense Enzyme Retrieval) provides a method for finding functionally related human-bacteria isozymes using learned dense vector representations (embeddings). 
+This huggingface repository contains the pre-trained models to reproduce the results and apply DEER to discover isozymes.
+
+The full codes are available at GitHub: https://github.com/WangJiuming/deer/tree/main.
+
+## Citation
+
+If you use the model in your research, please cite our paper with the following.
