| Research Abstract |
Regulation mechanisms of glutathione metabolism and polyamine metabolism were studied from the point of view that both metabolic pathways met at glutathionylspermidine. We studied extensively on the regulation of the Puu pathway, which is a catabolic pathway of putrescine. The affinity for putrescine of the repressor PuuR and PuuA, which is the first enzyme of the Puu pathway, are very low. This indicates that the Puu pathway is regulated, so that the pathway is active only in the presence of high putrescine concentration.
