  • Promotors T7, ptac and pTet
    • We tried to assemble some inserts with three different promotors to test which one is the best choice.
      • Plasmid isolation of ptac, ptac, T7, prkA, Hneap, SELAN, sRNA:pfkA and can
      • BioBrick Assembly (Suffix)
        • Backbones (digested with SpeI, PstI)
          • pSB1A2_T7
          • pSB1C3_ptac
          • pSB1K3_pTet
        • Inserts (digested with XbaI, PstI)
          • prkA
          • Hneap
          • SELAN
          • sRNA:pfkA
      • Transformation of all constructs with electrocompotetent cells
      • Colony PCR of pSB1C3_ptac_prkA, pSB1C3_ptac_Hneap, pSB1C3_ptac_SELAN and pSB1C3_ptac_sRNA:pfkA (VF-Primer, VR-Primer)
        • Annealing temperature: 55 °C
        • Bands as expected (~2500 bp (ptac_prkA), ~3200 bp (ptac_Hneap) ~3200 bp (ptac_SELAN) ~1700 bp (ptac_sRNA:pfkA))
      • Colony PCR of pSB1A2_T7_prkA, pSB1A2_T7_Hneap, pSB1A2_T7_SELAN and pSB1A2_T7_sRNA:pfkA (VF-Primer, VR-Primer)
        • Annealing temperature: 55 °C
        • Bands not as expected
        • → Showed in all cases a band 400 bp over the expected value. We tried to extract and transform the promotor from another distribution plate (2013)
      • Colony PCR of pSB1K3_pTet_prkA, pSB1K3_Tet_Hneap, pSB1K3_Tet_SELAN and pSB1K3_Tet_sRNA:pfkA (VF-Primer, VR-Primer)
        • Annealing temperature: 55 °C
        • Bands not as expected
        • → We tried it again.
      • Colony PCR of pSB1A2_T7 from the 2013 distribution plate (VF-Primer, VR-Primer)
        • Annealing temperature: 55 °C
        • Bands as expected (~300 bp)
      • Plasmid isolation of ptac_prkA, ptac_Hneap, ptac_SELAN, ptac_sRNA_pfkA and pSB1A2_T7

  • csoS1-4 (shell proteins csoS4AB and csoS1CAB)

  • can and csoS1-4

  • glpX

  • prkA and pHnCBscoS1D

  • RuBisCO
    • We tried to assemble both RuBisCO with pSB1C3_ptac_prkA
      • BioBrick Assembly (Suffix)
        • Backbone (digested with SpeI, PstI)
          • ptac_prkA
        • Inserts (digested with XbaI, PstI)
          • Hneap
          • SELAN
        • We assembled pSB1C3_ptac_prkA with Hneap respectively SELAN
      • Colony PCR (VF-Primer, VR-Primer)
        • Annealing temperature: 55 °C
          • pSB1C3_ptac_prkA_Hneap
            • Bands not as expected (too short).
            • → We will try to ligate pSB1C3_ptac_prkA and Hneap again.
          • pSB1C3_ptac_prkA_SELAN
            • Bands as expected (~4200 bp)
      • Plasmid isolation of ptac_prkA_Hneap and ptac_prkA_SELAN

  • can_csoS1-4 and csoS1D

  • Sequencing
    • csoS1D
      • Successful. We got the right sequence. The first part of the carboxysome is complete.
    • can
      • Five mutations. Another sequencing will follow.
    • csoS1-4
      • Not successful.
      • → Because of the wrong sequence the constructs pSB1C3_can_csoS1-4 and pSB1C3_can_csoS1-4_csoS1D are also incorrect and have to be made again.
    • glpX
      • Not successful. All samples showed the sequence of CFP from the backbone. We will start again, this time with pSB1C3_RFP for the backbone.
  • glpX

  • csoS1-4

  • Sequencing
    • can
      • Four to five mutations at the same positions as before. Maybe we got the wrong accession number, so we will further work with our can construct.
    • csoS1-4
      • Not successful.
    • SELAN
      • Not successful.
    • sRNA:pfkA
      • Not successful.
