(1) the peptase that hydrolyses proteins to peptones and (2) the ereptase that hydrolyses the peptones formed to amino acids as has been observed in case of the leaves of C. Infortunatum by me supports the views of Vines 11 but is not in accordance with the views of Wilistatter 12 wherein one single enzyme is supposed to be responsible for the hydrolysis of proteins into amino acids. [...] PROTEOLYTIC ENZYMES OF THE LEAVES OF C. INFORTUNATUM 7 In the above experiment the pH optima of proteinase actvity under the conditions adopted do not coincide with the iso-electric points of the respective substrates. [...] the fig) on the other was the observation of Vines on the leaTies of Phytolacca decandra.14 Attempts to purify the enzyme by precipitation of the aqueous solution with alcohol lead acetate or mercuric sulphate were not successful and resulted in the precipitation of inactive protlucts. [...] It has also been observed by Hopkins and Kelly 19 in case of the proteinase of green malt that phosphates and citrates the former of which are used for elution of the enzyme and both of which are used as buffers to stabilise pH inhibit the activity of the proteinase at pH 4.7. [...] For the present the activity of the proteinase has been investigated using ordinary cold aqueous extract of the twigs and young leaves as the active agent and in the absence of added buffers.
