 # **ZymCTRL**
 
-ZymCTRL (Enzyme Control) ([Paper presented @ NeurIPS Machine Learning for Structural Biology workshop - December 2022](https://www.mlsb.io/papers_2022/ZymCTRL_a_conditional_language_model_for_the_controllable_generation_of_artificial_enzymes.pdf)) 
+ZymCTRL (Enzyme Control) ([ see preprint ](https://www.biorxiv.org/content/10.1101/2024.05.03.592223v1)) 
 is a conditional language model for the generation of artificial functional enzymes. It was trained on the entire BRENDA database of enzymes, comprising over 37 M sequences. 
 Given a user-defined Enzymatic Commission (EC) number, the model generates protein sequences that fulfill that catalytic reaction. 
 The generated sequences are ordered, globular, and distant to natural ones, while their intended catalytic properties match those defined by users.
