Bacteriophage HK022.
Released HQ 2013
Coding region for the HK022 bacteriophage cI protein. cI binds to the HK022 pR regulator (BBa_R0050). It represses transcription of the protein encoded by the sequence 3' to the pR region. This coding sequence does not contain a RBS.</P>

It doesn't make sense in terms of the biology, for sure. In any case, the protein we characterized starts where Carlson and Little stated; as I recall, oR3 partially overlaps the start of cI. I have a vague memory of some possibly interesting biology, having to do with multicopy plasmids. I don't recall the findings themselves. Anyway, one possible explanation was that this extra N-terminal addition was made (e.g. from the pRE promoter, or from a message that arose from transcription around the entire plasmid), making a protein with altered functions. We never followed it up. <br> Good luck <br> John<br> <br> -- Original Message -- <br> Date: Sun, 19 Jan 2003 15:26:26 -0500 <br> Subject: hk022 cI start (naive question)? <br> Cc: elowitm@rockefeller.edu <br> To: jlittle@u.arizona.edu <br> From: Drew Endy <endy@MIT.EDU> <br> Hi John, I'm sitting here with Michael Elowitz and we're working through the sequence for HK022 cI. We noticed that the annotation from NC_002166 includes an "extra" 81 base pairs upstream of what we thought of as the actual start. It looks like this extra DNA extends into the PR regulatory region. We're wondering what's going on here? I'm guessing this is well documented somewhere. Thanks for any pointers/info! <br> Drew<P> It is unknown whether there is cross-talk between this repressor and Lambda cI regulatory region, 434 cI regulatory region and P22 regulatory region.

Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. <p>No secondary structures are formed in the given RBS region. Users should check for secondary structures induced in the RBS by upstream and downstream elements in the +50 to -50 region, as such structures will greatly affect the strength of the RBS.

<P> <P>In the naturally-occuring sequence there is a mismatch in the stem of the stem loop. This can be corrected via an A->G mutation (at position 40 -- sequence coordinate/not MFOLD coordinate). The above sequence does not reflect this mutation (but the MFOLD image does). This terminator's location cannot be found using some inverted repeat detectors like PALINDROME because it is too short and contains a mismatch. This one was found with the help of Tom Knight. It lies between two coding regions that point towards eachother.<P>

cI HK022
Promoter (HK022 cI regulated)
2003-01-31T12:00:00Z
2015-05-08T01:14:14Z
Bacteriophage HK022.
The pR regulatory region is a 98 base-pair sequence with standard BioBrick prefix and suffix sections on its ends. It contains two operator sites at which HK022 cI protein can bind cooperatively. The -35 and -10 regions from pR are included along with some flanking sequences. The cutoff for the 5' end of the regulatory region was placed just after the pM -10 region which promotes transcription of a gene upstream (thus the pM -10 region is not included). The cutoff for the 3' end of the regulatory region was placed immediately prior to the RBS. </p>

<P> <P>Suggested by Sri Kosuri and Drew Endy as a high efficiency terminator. The 5' end cutoff was placed immediately after the TAA stop codon and the 3' end cutoff was placed just prior to the RBS of Gene 1.4 (before AAGGAG).<P> Use anywhere transcription should be stopped when the gene of interest is upstream of this terminator.
