Abstract excerpt

This work reports the characterisation of the Azorhizobium caulinodans amtB gene, the deduced protein sequence of which shares similarity to those of several ammonium transporters. amtB is located downstream from glnK, a glnB-like gene. It is cotranscribed with glnK from an NtrC- and sigma54-dependent promoter. glnK and amtB insertion mutant strains have been isolated. Methylammonium uptake was assayed in these...
