The amount of glutamine found was, however, much less than that of the NH3 reacting. Similar relationships were found in Proteus morganii, Pr. vulgaris, Saccharomyces cerevisiae and S. ellipsoideus. Proteus morganii was, however, outstanding in possessing a powerful glutaminase which could easily be separated from the cells; in this it differed markedly from Pr. vulgaris. Glutaminase activity was also demonstrated in yeasts, where its occurrence has been previously a matter of dispute., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-2-2-186
