+# Dataset
+
+Swissprot is a high quality manually annotated protein database. The dataset contains annotations with the functional properties of the proteins. Here we extract proteins with Enzyme Commission labels.
+
+The dataset is ported from Protinfer: https://github.com/google-research/proteinfer.
+
+The leaf level EC-labels are extracted and indexed, the mapping is provided in `idx_mapping.json`. Proteins without leaf-level-EC tags are removed.
+
+
+## Example
+The protein Q87BZ2 have the following EC tags.
+
+    EC:2.-.-.-    (Transferases)
+    EC:2.7.-.-    (Transferring phosphorus-containing groups)
+    EC:2.7.1.-    (Phosphotransferases with an alcohol group as acceptor)
+    EC:2.7.1.30   (Glycerol kinase)
+
+We only extract the leaf level labels, here EC:2.7.1.30, corresponding to glycerol kinase.
