| + | Most bacteria, including Escherichia coli, have a coordinated inducible | ||

| + | genomes. The SOS response is triggered by the blockage of normal replication, | ||
| + | possibly caused by a lesion on the DNA. This event leads to the expression of | ||

| + | products have at least three roles in the cell, which are temporally regulated. | ||
| + | UmuD2C appears to have a role in delaying the cell cycle and DNA replication, | ||
| + | allowing time for accurate DNA repair processes to occur. After approximately | ||
| + | 20 minutes of UmuD 2 existing as a full-length protein, it self-cleaves to form | ||
| + | UmuD’ 2 . The new UmuD’ 2 C complex, together with several other proteins, is | ||
| + | capable of low fidelity translesion replication. Additionally, UmuD2 and UmuD’ | ||
| + | 2 interact physically with several of the replicative DNA polymerase subunits and | ||
| + | UmuD’ 2 C is capable of inhibiting homologous recombination while UmuD2C is | ||
| + | not. | ||

Result:
To have a dropdown for your own team copy over all of the content below. It might be needed to adjust a thing or two. Comments have been added throughout the code what must be changed.
Inspirational websites:
- [http://javascript-array.com/scripts/simple_drop_down_menu/ Most basic dropdown menu, with no submenu's]
- [http://jquery.com/ The javascript library used to add effects and optimise the dropdown]
- [http://www.tyssendesign.com.au/articles/css/centering-a-dropdown-menu/ How to center a ul list effectively]
The dropdown has been created and developed by the KULeuven team.

UmuD
Most bacteria, including Escherichia coli, have a coordinated inducible response to DNA damage known as the SOS response to combat damage to their genomes. The SOS response is triggered by the blockage of normal replication, possibly caused by a lesion on the DNA. This event leads to the expression of at least 40 SOS regulated genes, among which are the proteins of interest: a specialized DNA polymerase called DNA Pol V or UmuDC. The umuDC gene products have at least three roles in the cell, which are temporally regulated. UmuD2C appears to have a role in delaying the cell cycle and DNA replication, allowing time for accurate DNA repair processes to occur. After approximately 20 minutes of UmuD 2 existing as a full-length protein, it self-cleaves to form UmuD’ 2 . The new UmuD’ 2 C complex, together with several other proteins, is capable of low fidelity translesion replication. Additionally, UmuD2 and UmuD’ 2 interact physically with several of the replicative DNA polymerase subunits and UmuD’ 2 C is capable of inhibiting homologous recombination while UmuD2C is not.
N-terminal degradation tags (needed for T7, Lon protease based)UmuD
http://www.genesdev.org/cgi/content/full/12/24/3889
One obvious test of this hypothesis is an ability of these sequences to impart instability on an otherwise stable protein. To test this hypothesis, we constructed a plasmid (pKSD-PRP) expressing a chimeric gene encoding the first 40 amino acids of UmuD fused to a 7-amino-acid linker joined to the entire Streptoalloteichus hindustanus Ble protein. The S. hindustanus ble gene encodes a small, stable protein that provides resistance to the antibiotics of the phleomycin family. Furthermore, subsequent experimentation demonstrated that residues 1-29 of UmuD are sufficient to impart Lon recognition and degradation of the PRP similar to that seen with the 40-amino-acid fusion. The amino-terminal 40 amino acids of UmuD are sufficient to target the PRP for degradation by Lon in vivo. In contrast, the UmuD-PRP fusion is unstable in the lon+ background and displays a half-life of ~9 min.
Regulation of UmuD cleavage: role of the amino-terminal tail
http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6WK7-45S4955-4N&_user=877992&_rdoc=1&_fmt=&_orig=search&_sort=d&view=c&_acct=C000047079&_version=1&_urlVersion=0&_userid=877992&md5=5cf7322e67183cefdf18521b41317a32
By constructing chimeric UmuD proteins, we determined that the amino-terminal tail of the UmuD proteins proximal to the Cys24-Gly25 cleavage site is mainly responsible for the difference in UmuDStand UmuDEc cleavage rates. suggesting that most of the enhanced cleavage properties can be attributed to the N-terminal tail (residues 1 to 29) of UmuDSt. This region contains the cleavage site and not the active catalytic site of the protein, which leads us to conclude that UmuDSt is, in fact, cleaved more efficiently because it is a better substrate than UmuDEc.
