title: Effect of trypsin, S-adenosylmethionine and ethionine on L-serine sulfhydrase activity.
abstract: Trypsin causes an activation of serine sulfhydrase in the liver extracts from intact animals, but inhibits enzyme activity in the liver of ethionine treated rats. Trypsin also decreases an elevation of serine sulfhydrase activity caused by S-adenosylmethionine.
