Relationship between substrate activity and pKa value of phenols on sulfotransferase from Eubacterium A-44.
Biochem. Int. 28(4) , 725-34, (1992) The relationship between the kinetics of the enzyme activity and the structural features of phenolic donor and of acceptor substrates was investigated with a sulfotransferase from Eubacterium A-44, a human intestinal bacterium. The enzyme catalyzed the transf... |
