+# Lactate Dehydrogenase EC Number Predictor
+
+This is a free web app that predicts **EC numbers** for **lactate dehydrogenase** based on its **protein sequence**, using a custom AI model.
+
+## 🔬 How It Works
+
+- You enter a protein sequence (e.g., `MADQLTEEQIAEFKESFDKFKLLSHCLLVFHPDTELGALLTEAVIQKLREFLDGKNAVVVDSNGVNQFYTSWVKLVERQAKMMTNNQEIIWQQEKAAQEKYEEAEIAYIDLLEKVLAYSDLEKDWSFYVNSTGFHDIIVLEMARQGPLPVQYLKDKLKPGHSYGFDVFLPLKGIDNALKALGYKHPELIKWEAELQERIKKESGRLAQEVEGLYKPISEKLMKAFESDRKEFDKFIEKVSNL`)
+- The model returns the predicted EC number (e.g., `EC:1.1.1.27`)
