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.
