A complementary discussion is given of an earlier presented theory for viscometric determination of enzymic activity towards polymer substrates. Five different, purified endo‐1,4‐β‐glucanases from the fungus Sporotrichum pulverulentum have been characterised with respect to their molecular activities ( A m ) and Michaelis‐Menten constants ( K m ). The errors in the A m and K m values are discussed. The A m value seems to be more valuable as a distinguishing parameter than the K m value.
