IGEM:IMPERIAL/2008/Prototype/Wetlab/parts

• Chris D Hirst 21:40, 27 August 2008 (EDT):Had a go at uploading a sequence to the registry last night with mixed results, will check on this later and improve...

• Chris D Hirst 04:02, 28 August 2008 (EDT):Did some more work, Part:K143001 is now up on the parts registry, I'l put it's sister part (part:BBa_K143002) up asap. Before we upload anymore however I think we should write out ALL the basic parts and asign them codes to prevent problems downstream. Linking via the bbpart system (see iGEM teams page on OWW) doesn't actually work....

Tom (or James) would it be possible for one of you to make a nice diagram (or two interlinking ones - 1 for 5', 1 for 3') to signify integration sequences?

• Chris D Hirst 07:36, 28 August 2008 (EDT):Ok, the <bbpart></bbpart> system does work, but only on registry pages....

Numbering Rules!

• Chris D Hirst 07:53, 28 August 2008 (EDT):All Imperial iGEM 2008 parts are currently being placed in our allocated K413000-K413999 space; the divisions our below, so when adding a part try to ensure it is placed in the correct section. Also, I'll place a list of numbers at the bottom of this page, if people want specific numbers for specific parts, just claim them by writing the part next to the number

K413000-K413009 Integration sequences

K413010-K413019 Promoters

K413020-K413029 RBS

K413030-K413039 Coding Regions (Complete Genes - excludes those with coding sequences, they are separate)

K413040-K413049 Tags (ie. Secretion signals) and Tagged coding regions

Composite Parts:

Construction intermediates?:

K413090-K413100

Adding Parts to the Registry

The registry has a simple guide about adding parts on the following link. Before we start to add our parts we should collect the following information about each of our parts:

• A part name
• The DNA sequence of the part you are making
• A short description of the part
• A long description of the part, including references
• The source of the part, including references
• Design Considerations

Most of this information is on the wiki under the [| Sequence Page]. If the wet lab team could all contribute to adding these parts it would help speed things up. Once we have our parts we can then build up our constructs that we will be submitting to the registry.

Promoters

Promoter ctc

• Part name = promoter ctc
• Sequence =
• Promoter ctc is a sigma factor B dependent promoter found in B.subtilis. In B.subtilis endogenous sigma factor B is activated under mild stress from nutrient and physical stress response. The context with which we used the promoter ctc, was to take blue light as an input and give Polymerase Per Second(PoPS) as an output.

• Promoter ctc is a sigma factor B dependent promoter found in B.subtilis. In B.subtilis endogenous sigma factor B is activated under mild stress. These mild stress conditions can be generally split into nutrient stress response and physical stress response. Nutrient stress response is triggered by low levels of ATP and GTP and physical stress response is triggered by exposure to blue light, salt, heat, acid or ethanol[1]. The promoter ctc has been used previously as a read out for the activation of sigma factor B [2].
• The context with which we used the promoter ctc, was to take blue light as an input and give Polymerase Per Second(PoPS) as an output. To do this the other potential inputs need to be carefully controlled so that only blue light activated the sigma B and gives a PoPS output. In order to get sufficient sigma B activation by blue light the light receptor YtvA, part...., needs to be over expressed in B.subtilis [3].

• Source - The part was designed using the sequence from the B.subtilis genome and from previously published papers [2][3]. This sequence was then synthesised by Geneart.

• Design - Biobrick standard was applied to the promoter ctc sequence.

Integration Sequences

AmyE

5'

Name: 5’ AmyE Integration Sequence

Code: BBa_K143001

Sequence:

Short: 5’ integration sequence for the AmyE locus of B.subtilis

Long: Integration sequences allow DNA to be incorporated into the chromosome of a host cell at a specific locus using leading (5') and trailing (3') DNA sequences that are the same as those at a specific locus of the chromosome.The 5' integration sequence can be added to the front of a Biobrick construct and the 3' integration sequence specific for this locus (Part BBa_K143002) to the rear of the Biobrick construct to allow integration of the Biobrick construct into the chromosome of the gram positive bacterium B.subtilis.

The AmyE locus was the first locus used for integration into B.subtilis by Shimotsu and Henner[1] and is still commonly used in vectors such as pDR111[2], pDL[3] and their derivatives. Integration at the AmyE locus removes the ability of B.subtilis to break down starch, which can be assayed with iodine as described by Cutting and Vander-horn[4]. The 5' and 3' integration sequences for the AmyE locus were used to integrate the Imperial 2008 iGEM project primary construct into the B.sutbilis chromosome.

Source: The 5’ integration sequence was taken from the shuttle vector pDR111 which has been used in many studies on B.subtilis, in particular in the studies of transcriptional control[2, 5, 6]

Design: The AmyE integration sequence was taken from the vector after comparison by BLAST to the B.subtilis chromosome to identify the homologous sequences. The sequence present in both the host chromosome and the plasmid at the 5' end of the gene is the 5' sequence required for integration
