Mechanism I

We propose to link the riboflavin operon of Bacillus subtilis to plasmid puc18-ADH1 p+t(figure1). ADH1p(560bp) is a strong promoter of Yeast and ADH1t is the terminater corresponding to this promoter. The initial carrier of puc18-ADH1 p+t is PUC18. The construction of this plamid is: 
#Digest ADH1p with XbaI and BAMHI and link it to the relevant site of PUB18; 
#Digest ADH1t with KpnI and SacI and link it to the relevant site of PUC18.
