[Sodium dodecyl sulfate, concurrent inhibitor of several dehydrogenases]
Abstract:
The effect of sodium dodecyl sulfate on the activity of highly purified or crystalline enzymes has been studied. The enzymes were: lactate dehydrogenase (LDH), malate dehydrogenase (MDH). isocitrate dehydrogenase (ICDH), glucose-6-phosphate dehydrogenase (G6P-DH), lipase, alkaline phosphatase. Sodium dodecyl sulfate, always under the critical micellar concentration, shows a selective inhibitory effect. A kinetic analysis of the inhibitory action on LDH, MDH, ICDH and G6P-DH was also carried out.
