Studies on Amino Acids XII.

Although acylase activities in animal tissues, molds, bacteria and yeast have been clarified, nothing has been reported on the acylase activity in plants. Therefore, as a part of a series of studies intending to elucidate the biological significance of the presence of acylase activity, activity in plants was investigated.

As a result, the occurrence of acylase activity in plants such as vegetables, potatoes, pulses, cereals and fruits, has been confirmed for the first time. Besides the above higher plants a relatively higher acylase activity was also found in mushroom.
