EnzymeML implements the STRENDA Guidelines: For the complete machine-actable description of an enzymatic experiment, the STRENDA Guidelines were incorporated. In addition, metadata on the experiments and the kinetic model were included, resulting in a comprehensive data exchange format that comprises 71 attributes (Tab. S1). The current version of EnzymeML includes all STRENDA fields with a controlled vocabulary or values and excludes fields with plain text such as experiment methodology, in order to make EnzymeML structured and machine actable.
