Registry Code | Type | Sequence Description |
---|---|---|
Coding | RcsB is a receiver protein in a two component phosphorelay system, which acts as a positive regulator of a number of genes including capsule genes responsible for colanic acid production. This is via the activation of the ugd/cps operon which is required for capsule synthesis. | |
Coding | Dam (DNA Adenine Methylase) The methylase encoded by the dam gene ([http://en.wikipedia.org/wiki/Dam_(methylase) Dam methylase]) transfers a methyl group from S-adenosylmethionine to the N6 position of the adenine residues in the sequence GATC. When methylation occurs in the recognition site of a particular group of restriction endonuclease including MboI, this protects the DNA from cleavage. | |
Coding | Colanic acid global regulator ygiV (B3023) increases the production of colanic acid further in conjunction with RcsB by acting as a repressor for mcbR/yncC promoter. YncC/mcbR normally repress colanic acid overproduction so as to increase biofilm formation. | |
Coding | Waal Ligase is an enzyme responsible for the ligation of an O-antigen to the core oligosaccharide in the Gram-negative bacterium's outer membrane.
Unlike other exopolysaccharides, colanic acid does not naturally bind to the cell surface but rather forms a thick mesh between cells. While Waal Ligase usually links the O-antigen to the core oligosaccharide, in K-12 it links colanic acid to the core oligosaccharide. | |
