Fig. 1From: OmpA signal peptide leads to heterogenous secretion of B. subtilis chitosanase enzyme from E. coli expression systemMap of constructs used in this study. Nat-Csn (construct on left) was used for secretory expression of Csn via its native bacillus signal peptide, while OmpA-Csn (construct on right), comprised of the mature enzyme fused with the E. coli OmpA signal peptide that is a component of the pMY202 vectorBack to article page
