ANIMALS TREATED WITH CYSTEINE

Thus according to Braunshteïn [i] it has been established that this mould 

 synthesizes methionine by means of a chain of reactions in the reverse direction 

 to the formation of cysteine from methionine in animals. 



The investigations of Shiota & Clark [17] deal with the metabolism of meth- 

 ionine in bacteria. They note the appearance of methionine in Lactobacillus 

 arabinosus as a result of supplying L-cysteinc or DL-homocysteine in a sjrnthetic 

 medium.
