Glutamine uptake inZymomonas mobilis

Abstract

Glutamine was transported inZymomonas mobilis by a mechanism following Michaelis-Menten kinetics with a Km value for glutamine 8 x 10−5 M and a Vmax value of 15.4 nmol.mg−1, min−1 or 40 nmol.mg−1.min−1 for cells growing on complete medium or minimal medium respectively. The transport of glutamine was energy-dependent and more or less specific for glutamine when cell were grown on rich media. Evidence provided via spheroplasts suggests the possible involvement of a periplasmic component in this transport system.
