Effect of 4-azaleucine upon leucine metabolism in Salmonella typhimurium.


dl-4-Azaleucine (5 x 3(-3)m) added to exponentially growing cells of Salmonella typhimurium resulted in an abrupt cessation of growth lasting 4 to 8 hr followed by a resumption of division. The transitory nature of inhibition was not due to the instability or modification of the analogue or to a derepression of leucine-forming enzymes. Of many compounds… (More)
