A nanokatal (nkat) is an SI submultiple of the katal, equal to 10⁻⁹ katals. It quantifies the amount of a catalyst that increases the rate of a chemical reaction by one nanomole per second. It is primarily used in biochemistry to express the activity of enzymes in biological samples.
Heard on the job
The assay showed an enzyme activity of 4.2 nanokatals per milligram of total protein.
