Alkaline phosphatase D; Evidence 1a: Function experimentally demonstrated in the studied strain; enzyme.

Putative sensor diguanylate cyclase; Probable signaling protein whose physiological role is not yet known.

Putative diguanylate cyclase or phosphodiesterase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.

Putative hydrolase involved in biofilm formation; Plays a central, regulatory role in the late adaptive responses and affects the levels of many genes. May act via regulation of cAMP levels. Decreases the expression of motility genes and induces genes involved in biofilm formation, by controlling the expression of SlrR. Required for formation of intercellular nanotubes that bridge neighboring cells to allow molecular exchange. Plays a key role in directing the early stages of colony development. In vitro, has a metal-dependent phosphodiesterase activity against 2',3'-cAMP and 2',3'-cGM [...]

Putative cyclic diGMP binding protein; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative regulator.

Phosphodiesterase acting on cyclic dinucleotides; Has phosphodiesterase (PDE) activity against cyclic-di-AMP (c-di-AMP) and to a much lesser extent against cyclic-di-GMP (c-di-GMP) in the DHH/DHHA1 domains. Also has ATPase activity, probably via the GGDEF domain. Overexpression leads to increased sensitivity to methyl methanesulfonate (MMS) and H(2)O(2). Overexpression leads to extreme sensitivity to the beta-lactam antibiotic cefuroxime (CEF), probably dependent on PDE activity. May monitor cellular heme or NO levels. In B.subtilis c-di-AMP is a second messenger that mediates growth, [...]

Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.

Component of the twin-arginine pre-protein translocation pathway; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. Required for PhoD secretion. TatCd promotes membrane localization of TatAd via domain specific interactions. TatCd is required for stabile production of TatAd as well as for its maintenance; Belongs to the TatC family.

Component of the twin-arginine pre-protein translocation pathway; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. TatA could form the protein-conducting channel of the Tat system. Required for PhoD secretion. The cytosolic fraction of TatAd binds the precursor of PhoD; Belongs to the TatA/E family.
