BBa_C0050 1 cI HK022 cI repressor from phage HK022 (+LVA?) 2003-01-31T12:00:00Z 2015-08-31T04:07:23Z 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> false false _1_ 0 24 7 In stock false References (unparsed) here: <p>Carlson NG, Little JW.

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. true Reshma Shetty annotation1737 1 OR3 partial range1737 1 1 8 annotation1736 1 SsrA range1736 1 706 738 annotation1735 1 cI HK022 range1735 1 1 744 annotation1734 1 2 range1734 1 739 744 annotation2213990 1 Help:Barcodes range2213990 1 745 769 annotation7033 1 BBa_C0050 range7033 1 1 744 BBa_C0050_sequence 1 atggttcaacagaaagagcgtgaaactttctcgcagaggcttgcgctggcctgtgataaagcgggattacctttgcatggtaggcaggctgatttagctgtcaggcttaaggtcacaccaaaagccattagtaaatggttcaacggggagtcaataccaagaaaagacaagatggaatctctggcttcggtgctgggaactactgctgcatatctgcatggctatgctgatgatgacggtatcacggtaaatcatctatcaagatcaaatgattattatcgtgttgatgtattggatgttcaggcgagcgccgggccaggaaccatggtttccaatgaatttatagaaaagataagagcaattgaatatacgaccgagcaggcaagaattttatttaatggaaggccacaggaaagcgtaaaagtcatcacggttcgcggtgacagcatggagggaaccatcaatccgggagatgagatctttgttgatgtatccataacctgttttgatggcgatggcatttatgtgtttgtatacgggaaaacaatgcacgttaagcgcctgcaaatgcaaaagaacaggcttgccgtcatctctgacaatgccgcttatgatcgatggtacatagaagaaggtgaagaagagcaacttcacattctagccaaagtcctcattaggcagtcaatcgattacaagcgattcggagctgcaaacgacgaaaactacgctttagtagcttaataaccctgatagtgctagtgtagatccc igem2sbol 1 iGEM to SBOL conversion Conversion of the iGEM parts registry to SBOL2.1 Chris J.
