Overview

Part BBa_K2684000 was improved from previous part BBa_K1336002. Our team made a point mutation to eliminate the EcoR1 cutting site so that we can meet the standard of RFC10, a commonly-used standard for interchangeable parts which are based on idempotent assembly. We tested the enzyme activity of our part based on the weight of our sample. Formula: laccase activity (nmol/min/g) = ΔA /ε(ABTS mmolar extinction coefficient) / d * V (total volume of reaction) / V (volume of sample in the reaction, 0.025mL) / W (sample mass, g) * V (extracted liquid added, 1mL) / T (reaction time, 3 minutes) = 130 *ΔA / W. The result is shown as following:

The improvement is valid since it was normally produced. Thus, this part is the favorite one of our team.
