1. Characterization of protein-protein interactions important for the regulation of the quorum-sensing process in Xanthomonas axonopodis pv citri. / Caracterização bioquímica de interações proteína-proteína relacionadas com o mecanismo de quorum-sensing do Xanthomonas axonopodis pv citri
Parte da produção de fatores de virulência em bactérias do gênero Xanthomonas esta sob controle de um grupo de genes localizados no locus rpf (regulation of pathogenicity factors), que respondem ao aumento da densidade celular num processo chamado quorum sensing. Os genes que codificam as proteínas do sistema Rpf de Xanthomonas axonopodis pv citri (Xac

2. Crystal Structures of YkuI and Its Complex with Second Messenger Cyclic Di-GMP Suggest Catalytic Mechanism of Phosphodiester Bond Cleavage by EAL Domains*
Cyclic di-GMP (c-di-GMP) is a ubiquitous bacterial second messenger that is involved in the regulation of cell surface-associated traits and the persistence of infections. Omnipresent GGDEF and EAL domains, which occur in various combinations with regulatory domains, catalyze c-di-GMP synthesis and degradation, respectively. The crystal structure of full

3. Three cdg Operons Control Cellular Turnover of Cyclic Di-GMP in Acetobacter xylinum: Genetic Organization and Occurrence of Conserved Domains in Isoenzymes
Cyclic di-GMP (c-di-GMP) is the specific nucleotide regulator of β-1,4-glucan (cellulose) synthase in Acetobacter xylinum. The enzymes controlling turnover of c-di-GMP are diguanylate cyclase (DGC), which catalyzes its formation, and phosphodiesterase A (PDEA), which catalyzes its degradation. Following biochemical purification of DGC and PDEA, genes encodi

4. Structural basis of activity and allosteric control of diguanylate cyclase
Recent discoveries suggest that a novel second messenger, bis-(3′→5′)-cyclic di-GMP (c-diGMP), is extensively used by bacteria to control multicellular behavior. Condensation of two GTP to the dinucleotide is catalyzed by the widely distributed diguanylate cyclase (DGC or GGDEF) domain that occurs in various combinations with sensory and/or regulatory
