Activating Compound

Activating Compound Comment Organism Structure
epithiospecifier protein protein factor that alters the outcome of the enzyme catalyzed reaction. Epithiospecifier protein is a true enzyme rather than an allosteric cofactor of myrosinase. No stable association between epithiospecifier protein and myrosinase occurs, but some proximity of both is required for epithionitrile formation to occur Sinapis alba
nitrile-specifier protein protein factor that alters the outcome of the enzyme catalyzed reaction. Nitrile-specifier protein is a true enzyme rather than an allosteric cofactor of myrosinase Sinapis alba
