Abstract Uncoupling of biological nitrogen fixation from ammonia assimilation is a prerequisite step for engineering ammonia excretion and improvement of plant-associative nitrogen fixation. In this study, we have identified an amino acid substitutio

ABSTRACT A fundamental question in microbial physiology concerns why organisms prefer certain nutrients to others. For example, among different nitrogen sources, ammonium is the preferred nitrogen source, supporting fast growth, whereas alternative n

Glutamine synthetase (GS) is the central enzyme for nitrogen assimilation in Escherichia coli and is subject to reversible adenylylation (inactivation) by a bifunctional GS adenylyltransferase/adenylyl-removing enzyme (ATase). In vitro, both of the o

The BBK32 protein binds to host extracellular ligand fibronectin and contributes to the pathogenesis of Borrelia burgdorferi. Here we showed that expression of the BBK32 gene is influenced by multiple environmental factors and that its regulation is

Bacterial histidine kinases have been proposed as targets for the discovery of new antibiotics, yet few specific inhibitors of bacterial histidine kinases have been reported. We report here a novel thienopyridine (TEP) compound that inhibits bacteria

A flagellar gene cluster fragment includingflbD ofAzospirillum brasilense was cloned and sequenced. TheflbD mutant strain was found to be nonmotile—losing both polar and lateral flagella (Fla−Laf−). Motility and flagella were regained by comple

Protein phosphoaspartate bonds play a variety of roles. In response regulator proteins of two-component signal transduction systems, phosphorylation of an aspartate residue is coupled to a change from an inactive to an active conformation. In phospha

The crystal structure of BeF -activated CheY, with manganese in the magnesium binding site, was determined at 2.4-A resolution. BeF bonds to Asp57, the normal site of phosphorylation, forming a hydrogen bond and salt bridge with Thr87 and Lys109, res

The chemotactic regulator CheY controls the direction of flagellar rotation in Escherichia coli. We have determined the crystal structure of BeF3−-activated CheY from E. coli in complex with an N-terminal peptide derived from its target, FliM. The

Two-component systems, sensor kinase-response regulator pairs, dominate bacterial signal transduction. Regulation is exerted by phosphorylation of an Asp in receiver domains of response regulators. Lability of the acyl phosphate linkage has limited s
