catalytic activity fraction

of an isozyme
also contains definition of: catalytic fraction
https://doi.org/10.1351/goldbook.C00884
Quotient of the catalytic activity of the isozyme and the catalytic activity of all the isozymes of the same enzyme in the system.
Notes:
  1. The term catalytic fraction is accepted for use in clinical chemistry.
  2. The definition is based on the definitions of catalytic activity and fraction.
  3. The definition also applies to other multiple forms of an enzyme that are not isoenzymes.
