Fig. 1

Sequence of plasmid pSK2 in the region of vgb and the integrated amoC P1 promoter. The amoC promoter is highlighted in yellow, with the flanking HindIII sites highlighted in red. The native vgb promoter region is highlighted in green, and the vgb coding sequence, beginning with the ATG start codon and ending with the TAA stop codon, is highlighted in turquoise.
