1. lODOACETATE AND lODOACETAMIDE 



Table 1-4 

 Inhibition of Alcohol Dehydrogenase by Iodoacetate 



" The enzymes are all NAD-dependent unless otherwise noted. 



* This enzyme is a new type of alcohol dehydrogenase, perhaps better called an 

 alcohol : cy tochrome-553 reductase . 



= It was stated by DeMoss (1955) that this enzyme is inhibited 100% by 1 mM 

 iodoacetate after 7 min incubation with respect to NADP reduction; the discrepancy 

 between these figures and those in the table is not explained.
