The HasA coding sequence is originally found in the Serratia marcescens and to construct this part, we used the HasA gene that is from the part BBa K1897000 which was synthesised based on the gene sequence from the National Center for Biotechnology Information (NCBI) database (http://www.ncbi.nlm.nih.gov/nuccore/X81195.2). The Promoter, RBS and terminator are biobrick parts that were obtained from the Distribution kits from iGEM.

Design Notes

The presence of a hexa histidine tag would allow for easy protein purification and detection using anti-his antibodies. The promoter BBa_K525998 was chosen as we wished to induce high levels of HasA for purification thus we required a T7 promoter that could be used to induce expression at high levels in E. coli strain BL21(DE3). The terminator BBa_B0015 was chosen as it is commonly used and has a high efficacy.
