EnzymeML is a free and open standard based XML markup interchange format for enzyme kinetics. The purpose of EnzymeML is to store and exchange enzyme kinetic data between databases, instruments and software tools. EnzymeML will allow scientists to share their experimental protocols and results even if they are using different instruments, electronic laboratory notebooks, or databases.

EnzymeML originated by members of the STRENDA Project. The development is jointly led by Juergen Pleiss, Neil Swainston and Santiago Schnell.
