Characterization of the precursor form of the exocellular levansucrase from Bacillus subtilis.
Expression of the cloned levansucrase gene (sacB) was demonstrated in E. coli minicells by assay of the enzyme in crude extracts, SDS-polyacrylamide gel electrophoresis and immunoblotting. The existence of a precursor form of the enzyme of MW 53000 was also demonstrated and confirmed by the DNA sequence corresponding to the NH2 terminal region of the protein.
