MsCHI

MsCHI is the coding sequence that codes for Medicago sativa chalcone isomerase in Medicago sativa. It is the Isomerase involved in the flavonoid biosynthesis. In nature, it has highest expression in young root tips. Medicago sativa chalcone isomerase catalyzes the intramolecular cyclization of bicyclic chalcones into tricyclic (S)-flavanones. Responsible for the isomerization of 4,2',4',6'-tetrahydroxychalcone (also termed chalcone) into naringenin. Optimum pH is 7-8.5 with 4,2',4'-trihydroxychalcone as substrate, at 25 degrees Celsius. In terms of catalytic activity, a chalcone = a flavanone. EC:5.5.1.6 In our project, the sequence will express chalcone isomerase to convert p-Coumaroyl-CoA into naringenin.

The construction schematic of MsCHI sequence demonstrated in Fig.7. The initiation of the MsCHI sequence is done by promoter pAOX1, with termination done by tTDH1. The sequence ConL3 and ConRE are connector sequences within the Level 1 plasmid assembly. Furthermore, type9-KVF and type9-VR are imposed to enact selection through colonies PCR, results shown in Fig.7 B The band length 2021bp match with expectations. The sequence analysis results show no significant mutations or deletions, representing the success of the assembly.
