| Registry Code | Type | Sequence Description |
|---|---|---|
| Coding | RcsB is a receiver protein which acts as a positive regulator of a number of genes including capsule genes responsible for colanic acid production. | |
| 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, 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 [http://en.wikipedia.org/wiki/O_antigen#O-antigen O-antigen] to the core [http://en.wikipedia.org/wiki/Oligosaccharide oligosaccharide] in the Gram-negative bacterium's outer membrane. | |
| Coding | OtsA is the first of two required in the conversion of glucose to [http://en.wikipedia.org/wiki/Trehalose trehalose].
This enzyme catalyses the following reaction: UDP-glucose + D-glucose 6-phosphate -> UDP + alpha,alpha-trehalose 6-phosphate | |
| Coding | OtsB This enzyme is the second of two required for the conversion of glucose to [http://en.wikipedia.org/wiki/Trehalose trehalose].
This enzyme catalyses the following reaction: alpha,alpha-trehalose 6-phosphate + H2O -> alpha,alpha-trehalose + phosphate | |
| Coding | [http://en.wikipedia.org/wiki/Cellulase Cellulase] mainly catalyses the reactions that changes crystalline [http://en.wikipedia.org/wiki/Cellulose cellulose] to [http://en.wikipedia.org/wiki/Cellobiose cellobiose] and then finally to glucose. This cellulase is protease resistant. | |
| Coding | [http://en.wikipedia.org/wiki/Phenylalanine_hydroxylase Phenylalanine hydroxylase] is the enzyme that breaks down [http://en.wikipedia.org/wiki/Phenylalanine phenylalanine] to [http://en.wikipedia.org/wiki/Tyrosine tyrosine]. Deficiency of this enzyme activity results in the autosomal recessive disorder [http://en.wikipedia.org/wiki/Phenylketonuria phenylketonuria]. | |
| Coding | Restriction enzyme [http://www.thelabrat.com/restriction/DpnII.shtml DpnII] is a Type II restriction enzyme that recognises the sequence GATC. Its activity can be blocked by dam methylation. | |
| Coding | Restriction enzyme [http://www.thelabrat.com/restriction/TaqI.shtml TaqI] is a Type II restriction enzyme that recognises the sequence TCGA. Its activity can be blocked by dam methylation. | |
| Coding | This Lamda cI repressor has a cI857 mutation that results in denaturation of the repressor when the temperature is raised from 30 to 42°C, thereby allowing lambda promoter expression.
When the temperature is raised, typically to 42°C, the functionality of the protein is lost and the cI repressor is no longer able to bind to the operators on its promoter. Therefore, lambda promoter expression increases. | |
| Regulatory | Lambda promoter (cIts responsive) is different from the common lambda promoter in that it is able to be repressed by the temperature sensitive cI protein (BBa_K200011). When it is not being repressed after 42°C induction, it acts as a strong promoter. | |
