Mechanism II
From 2007.igem.org
Yeast can produce riboflavin itself, but it can only supply its own metabolism without accumulation. There are 6 genes related to the riboflavin production. The patyway of riboflavin synthesis is showed below:
We propose to change the prmoters related to riboflavin synthesis of Yeast to strong promter ADH1. The two-step-gene replacement method is used in our project. Take RIB1 as an example. Take the RIB1gene as three regions: region1, region2 and region2 (figure5)
