Design Notes

Coding sequence for tphB enzyme was taken from Uniprot: Q3C1E1 and nucleotide sequence was codon-optimised for expression in E. coli. BioBrick prefix, containing restriction sites for EcoRI and XbaI, and suffix with sites for restriction by SpeI and PstI were added on ends of the construct for easier insertion into vectors. Our construct was also designed with RBS, T7 promoter and terminator and lac operator for optimal induction of protein expression (Shepherd et al. 2017, Du et al. 2012) and C-terminal histidine tag for enzyme purification on immobilized metal affinity chromatography
