Expression of glnB and a glnB-Like Gene (glnK) in a Ribulose Bisphosphate Carboxylase/Oxygenase-Deficient Mutant of Rhodobacter sphaeroides

Qian, Yilei, Tabita, F. Robert

In a ribulose 1,5-bisphosphate carboxylase/oxygenase (RubisCO)-deficient mutant of Rhodobacter sphaeroides, strain 16PHC, nitrogenase activity was derepressed in the presence of ammonia under...

Identification of a DtxR-Regulated Operon That Is Essential for Siderophore-Dependent Iron Uptake in Corynebacterium diphtheriae

Qian, Yilei, Lee, John H., Holmes, Randall K.

The diphtheria toxin repressor (DtxR) uses Fe2+ as a corepressor and inhibits transcription from iron-regulated promoters (IRPs) in Corynebacterium diphtheriae. A new IRP, designated IRP6, was cloned...

Cloning, Characterization, and Functional Expression of the Klebsiella oxytoca Xylodextrin Utilization Operon (xynTB) in Escherichia coli†

Qian, Yilei, Yomano, L. P., Preston, J. F., Aldrich, H. C., Ingram, L. O.

Escherichia coli is being developed as a biocatalyst for bulk chemical production from inexpensive carbohydrates derived from lignocellulose. Potential substrates include the soluble xylodextrins...
