摘要

The effect of 1-butanesulfonic acid sodium salt and sodium dodecyl sulfate on the activity of highly purified and crystalline enzymes with marked differences in structure and function has been studied. The enzymes were: alcohol dehydrogenase; lactate dehydrogenase; malate dehydrogenase; isocitrate dehydrogenase; glucose-6-phosphate dehydrogenase; lipase; alkaline phosphatase. While 1-butanesulfonic acid sodium salt, at the studied concentrations, resulted generally inactive, sodium dedecyl sulfate showed a selective inhibitory effect, always under the critical micellar concentration. A kinetic analysis of the inhibitory action was also carried out.
