• Huang Lab

    Our research interests include molecular mechanism of proton-coupled mass transfer across cellular membrane and development of protein pKa predictor.

  • pH and pKa

    pH represents solution acidity and plays a key role in many biological processes via protonation or deprotonation of key ionizable residues in a protein where titration equilibria are determined by pKa values which can be measured typically by NMR or estimated by a theoretical model.

  • About DeepKa

    DeepKa, a deep learning-based protein pKa predictor, is built based on pKa's calculated by continuous constant pH molecular dynamics simulations.
