Abstract

ABSTRACT Sequencing the glnA genes of two chemically induced Azospirillum brasilense glutamine synthetase mutants revealed an Arg→Cys mutation, corresponding to the glutamate binding site, in one mutant and an Asp→Asn mutation, corresponding to the ammonium binding site, in the second mutant. The phenotypic changes in these mutants are discussed in relation to their genotypes.
