Two-component response regulator AlgB; Member of the two-component regulatory system AlgB/KinB involved in regulation of alginate biosynthesis genes. Positive regulator of the alginate biosynthetic gene AlgD.

Phosphomannomutase AlgC; Highly reversible phosphoryltransferase. The phosphomannomutase activity produces a precursor for alginate polymerization, the alginate layer causes a mucoid phenotype and provides a protective barrier against host immune defenses and antibiotics. Also involved in core lipopolysaccaride (LPS) biosynthesis due to its phosphoglucomutase activity. Essential for rhamnolipid production, an exoproduct correlated with pathogenicity. Required for biofilm production. The reaction proceeds via 2 processive phosphoryl transferase reactions; first from enzyme-phospho-Ser-1 [...]

Two-component response regulator AlgB; Member of the two-component regulatory system AlgB/KinB involved in regulation of alginate biosynthesis genes. Positive regulator of the alginate biosynthetic gene AlgD.

GDP-mannose 6-dehydrogenase AlgD; Catalyzes the oxidation of guanosine diphospho-D-mannose (GDP-D-mannose) to GDP-D-mannuronic acid, a precursor for alginate polymerization. The alginate layer causes a mucoid phenotype and provides a protective barrier against host immune defenses and antibiotics.

Two-component response regulator AlgB; Member of the two-component regulatory system AlgB/KinB involved in regulation of alginate biosynthesis genes. Positive regulator of the alginate biosynthetic gene AlgD.

Alginate o-acetyltransferase AlgI; Together with AlgJ and AlgF, forms an inner membrane complex which probably interacts with the alginate polymerization-transport complex and adds acetyl groups at the O-2 and O-3 positions of mannuronate residues. Acetylation of alginate is important for the architecture of biofilms and increases resistance to opsonic killing in the host.

Two-component response regulator AlgB; Member of the two-component regulatory system AlgB/KinB involved in regulation of alginate biosynthesis genes. Positive regulator of the alginate biosynthetic gene AlgD.

Poly(beta-d-mannuronate) lyase precursor AlgL; Catalyzes the depolymerization of alginate by cleaving the beta-1,4 glycosidic bond between two adjacent sugar residues via a beta-elimination mechanism. May serve to degrade mislocalized alginate that is trapped in the periplasmic space. Acts preferentially on non-acetylated alginate or its precursor mannuronan. Is able to catalyze cleavage adjacent to either mannuronate or guluronate residues in alginate. Exhaustive digestion of alginate by AlgL generates dimeric and trimeric products. In addition to its enzymatic function, AlgL appears [...]

Two-component response regulator AlgB; Member of the two-component regulatory system AlgB/KinB involved in regulation of alginate biosynthesis genes. Positive regulator of the alginate biosynthetic gene AlgD.

Alginate regulatory protein AlgP; The promoter for a critical alginate biosynthetic gene, AlgD, encoding GDP-mannose dehydrogenase, is activated only under conditions reminiscent of the cystic fibrosis lung (i.e. under high osmolarity), and at least two regulatory genes, AlgP and AlgQ, have been implicated in this activation process.

Two-component response regulator AlgB; Member of the two-component regulatory system AlgB/KinB involved in regulation of alginate biosynthesis genes. Positive regulator of the alginate biosynthetic gene AlgD.

Sigma factor AlgU; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor regulates genes such as algD, involved in alginate biosynthesis.

Two-component response regulator AlgB; Member of the two-component regulatory system AlgB/KinB involved in regulation of alginate biosynthesis genes. Positive regulator of the alginate biosynthetic gene AlgD.

Alginate biosynthesis protein AlgX; Plays two roles in the biosynthesis of the exopolysaccharide alginate: protects alginate from degradation as the polymer traverses the periplasm, and also plays a role in its O-acetylation. Acetylation of alginate causes the cells in the biofilm to adhere better to lung epithelium, form microcolonies, and resist the effects of the host immune system and/or antibiotics. Displays a low acetylesterase activity in vitro using a pseudosubstrate, 3-carboxyumbelliferyl acetate. Probably has acetyltransferase activity in vivo. Belongs to the AlgX family.

Two-component response regulator AlgB; Member of the two-component regulatory system AlgB/KinB involved in regulation of alginate biosynthesis genes. Positive regulator of the alginate biosynthetic gene AlgD.

Alginate and motility regulator Z; Functions as both a transcriptional activator and repressor of multiple genes encoding virulence factors as well as genes involved in environmental adaptation. Plays a role in alginate production via the activation of AlgD which is the first gene in the alginate biosynthetic operon. Regulates also the transcription of genes responsible for type IV pili localization and twitching motility. Mediates transition of P.aeruginosa biofilm infections from colonizing to chronic biofilms through repression of the psl operon. Represses also its own transcription [...]
