Figure 1From: Production of a modified peptide clavanin in Pichia pastoris: cloning, expression, purification and in vitro activitiesPlasmid vector map. The constitutive system was developed using the plasmid pGAPZαB, which contains the PGAP promoter. The inducible system was constructed using the pPICZαA, which contains the PAOX promoter. HIS his-tag, Trx thioredoxin E. coli gene, Cla clavanin gene, AOX TT terminator.Back to article page
