Cyclic-di-gmp phosphodiesterase, flhdc-regulated; Involved in the control of the switch from cell motility to adhesion via regulation of cellular levels of cyclic-di-GMP (c-di-GMP) . Part of a signaling cascade that regulates curli biosynthesis. The cascade is composed of two c-di-GMP control modules, in which c-di-GMP controlled by the DgcE/PdeH pair (module I) regulates the activity of the DgcM/PdeR pair (module II), which in turn regulates activity of the transcription factor MlrA and expression of the master biofilm regulator csgD . Effect on flagella is controlled via the c-di-GMP [...]

Oxygen sensor, c-di-gmp phosphodiesterase, heme-regulated; Heme-based oxygen sensor protein displaying phosphodiesterase (PDE) activity toward c-di-GMP in response to oxygen availability. Involved in the modulation of intracellular c-di-GMP levels, in association with DosC which catalyzes the biosynthesis of c-di-GMP (diguanylate cyclase activity). Cyclic-di-GMP is a second messenger which controls cell surface-associated traits in bacteria. Has very poor PDE activity on cAMP but is not active with cGMP, bis(p-nitrophenyl) phosphate or p-nitrophenyl phosphate . Via its PDE activity on [...]

Putative membrane-anchored cyclic-di-gmp phosphodiesterase, regulator of cellulose production; Phosphodiesterase (PDE) that catalyzes the hydrolysis of cyclic-di-GMP (c-di-GMP) to 5'-pGpG (By similarity). May serve as a negative regulator of cellulose synthesis (as has been suggested for S.typhimurium); overexpression inhibits cell aggregation in strains able to produce adhesive curli fimbriae. Cyclic-di-GMP is a second messenger which controls cell surface-associated traits in bacteria

Merr family transcriptional regulator, activator of the csg genes; Activates transcription of csgD, the master regulator of biofilm formation, by binding to its promoter region Also controls the transcription of cadC and ibaG . Part of a signaling cascade that regulates curli biosynthesis. The cascade is composed of two c-di-GMP control modules, in which c-di-GMP controlled by the DgcE/PdeH pair (module I) regulates the activity of the DgcM/PdeR pair (module II), which in turn regulates activity of the transcription factor MlrA

Putative c-di-gmp phosphodiesterase pdek; Phosphodiesterase (PDE) that catalyzes the hydrolysis of cyclic-di-GMP (c-di-GMP) to 5'-pGpG

Putative membrane-anchored diguanylate cyclase; Catalyzes the synthesis of cyclic-di-GMP (c-di-GMP) via the condensation of 2 GTP molecules (By similarity). Cyclic-di-GMP is a second messenger which controls cell surface-associated traits in bacteria. Involved in the regulation of cellulose production

Cyclic di-gmp phosphodiesterase pder; Part of a signaling cascade that regulates curli biosynthesis. The cascade is composed of two cyclic-di-GMP (c-di-GMP) control modules, in which c-di-GMP controlled by the DgcE/PdeH pair (module I) regulates the activity of the DgcM/PdeR pair (module II), which in turn regulates activity of the transcription factor MlrA and expression of the master biofilm regulator csgD . PdeR acts as a trigger enzyme that connects modules I and II. It inhibits DgcM and MlrA by direct interaction. Inhibition is relieved when PdeR binds and degrades c-di-GMP genera [...]

Luxr family transcriptional regulator, csgab operon transcriptional regulatory protein; The master regulator for adhesive curli fimbriae expression; necessary for transcription of the csgBAC/ymdA operon. Plays a positive role in biofilm formation. May have the capability to respond to starvation and/or high cell density by activating csgBA transcription. Low-level constitutive expression confers an adherent curli fimbriae- expressing phenotype, up-regulates 10 genes and down-regulates 14 others

anti-FlhD4C2 factor, inactive EAL family phosphodiesterase; Upon overexpression acts as a novel anti-FlhC(2)FlhD(4) factor, decreasing its DNA-binding activity, able to negatively regulate expression of flagellar class II operons including FliC
