The enzyme unit (U = µmol/min) is outdated, use katal (kat = mol/s, 1 U = 16.7 nkat) instead. And an FPU is a floating point unit, a piece of computer hardware.

What is FPU?

See the attachment for enzyme activity expression

Engelbert Buxbaum and Joseph Kreit Thanks for your help.

The FPU is normally consider for cellulase enzymes where it represent the filter paper unit or the cellulase enzyme activity.
