+# Description
+β-Lactamase Prediction studies the activity among first-order mutants of the TEM-1 beta-lactamase protein. The target *y* ∈ *R* is the experimentally tested fitness score which records the scaled mutation effect for each mutant.
+
+# Splits
+
+**Structure type:** None
+
+The dataset is from [**PEER: A Comprehensive and Multi-Task Benchmark for Protein Sequence Understanding**](https://arxiv.org/abs/2206.02096). We follow the original data splits, with the number of training, validation and test set shown below:
+
+- Train: 4158
+- Valid: 520
+- Test:  520
+
+# Data format
+
+We organize all data in LMDB format. The architecture of the databse is like:
+
+**length:** The number of samples
+
+**0:** 
+
+- **seq:** The structure-aware sequence
+- **fitness:** fitness label of the sequence
+
+**1:**
+
+**···**
