Structures of recombinant plasmids. Secretory enzymes (xylanase, glucanase, and mannanase) corresponding genes were constructed to contain a full-length or only mature part as represented by arrows. DNA regions corresponding to signal peptides were depicted by a gray box located between the T7 promoter (triangles) and the mature part. β-1,4-xylanase gene; xyn, β-1,4-glucanase; cel, β-mannanase; man, benzoylformate decarboxylase; dpgB, benzaldehyde dehydrogenase; dpgC, and d-phenylglycine aminotransferase; dpgA.
