BBa_K609001 1 BBa_K609001 acid induced promoter rcfB + repressor lacR of lac operon 2011-09-30T11:00:00Z 2015-05-08T01:12:53Z The part is designed to let Lactobacillus bulgaricus stop producing lactic acid when the external pH declines to 5.5 or lower. When the external pH value declines to 5.5, rcfB promoter will be highly upregulated. Along with that, the lacR gene, which is downstream of rcfB, will be highly transcribed. The large translation of LacR, the repressor of lac operon in Lactobacillus delbrueckii, will inhibit the use of lactose in the bacteria. false false _781_ 0 8592 9 Not in stock false The rcfB promoter is found in Lactococcus lactis IL1403, while the lacR gene is from Lactobacillus. delbrueckii subsp. lactis. false Ke Liu annotation2148327 1 lacR range2148327 1 113 1111 annotation2148328 1 rcfB range2148328 1 31 112 BBa_K609001_sequence 1 gtttcttcgaattcgcggccgcttctagagttttaatgatttacataaaaaatgatataatgaaatggctacagccttatataggcgaataaatgaacaaattagcgagtagatggctactatccgcgaagttgctaaggctgctggcgtttcaccagctactgtttcacgcgttctgaactacgaccaaactctgtcagttaacgaagctactcgccaaaagatcttcaagactgctgaagctatgcactaccacaagtcacgcaagactcgcaagtcaaagcaaaagcgcctggctatctgcctgtggtgcgaccaagaccaagaaatcaaggacctgtactactactcaatccgcacttcagctcaagctgaagctaagaagcaaggcctggaatcacaagttatctacccagctgacccactgccagacccagctgctctgtcaggcatcatcatgatcggctaccaacaatactcaccagaccgcctgaacgaagttaagaagtcaggcctgccactggttttcgttgacactgacactctgaagctgggctactgctcagttgttgctgacttcggccaagctatgcaagaagctctggaagttttctggggccaaggccgcgaacgcatcgctctgctggacggcgacctggactcaaacttcgacaagaacaacctggttgacttccgcttccgcgactacaagaagtcactggctgctcgcggccaatacgacccagacctggtttacgttggcaacttcactccacaatcaggctacgaagctatcaaggaagctctgaagtcaggctcattcccaaaggctctgatcgctgctaacgacgctatggctatcggcgctctgaaggctttcaaggaagctggcatcaaggttccagaagacgtttcactgatctcattcaacgacactactgctgctgagttcgctaacccagctctgacttcagttcacgttgaaactcaacaaatgggccgcgcttcagttaaggttatgaaggacctgctggacgacgacgaagctggcacttacaaggttactttcccaactaagctggtttaccgcgaatcatgcccaaaggcttaatactagtagcggccgctgcaggaagaaac igem2sbol 1 iGEM to SBOL conversion Conversion of the iGEM parts registry to SBOL2.1 Chris J.
