The first section of the part collection (BBa_K4271000 ~ BBa_K4271003, BBa_K4271015, BBa_K4271016) is designed for the phosphate elimination functions, the increase of hydrolysis and absorbance of organic phosphate, in bacterial cells. The parts in the second section of the collection (BBa_K4271004 ~ BBa_K4271011, BBa_K4271018, BBa_K4271019) are designed for the construction of biosensors that could help monitor the functions of the parts in the first section. This is a comprehensive collection that includes both the parts with functions and the parts that assist the measurement of the said functions. This combination not only provides methods for phosphate elimination in different fields of application but also allows future users to more easily replicate experiments that could monitor the effectiveness of their constructs designed with these parts. Our part collection also included the integration of ideas from our partnership with another iGEM team, particularly in the use of a degradation tag (BBa_M0052) to improve the experimental results of biosensors.
