A glutamine transaminase activity has been identified in Saccharomyces cerevisiae, and the existence of the omega-amidase activity previously described in this yeast has been confirmed. The glutamine transaminase utilizes different 2-oxo acids as substrates, including pyruvate and glyoxylate, and is regulated by the available nitrogen source. The glutamine transaminase activity decreases when lysine or glycine is added to the medium; the inhibition by lysine diminishes under microaerophilic… CONTINUE READING
