The native promoter of a xylanase gene isolated from Closlriditrm therntocelhrm was replaced with a strong promoter screened from Bacillus strbtilis chromosomes. A part of the C-terminal region of the gene which is not related to the xylanase activity was removed. With the modified xylanase gene, B.

โฆ Synopsis
A gene for aUosteric lactate dehydrogenase (LDH) of Lactobacillus casei ATCC393 was transferred into Bacillus subtHis. The LDH was produced in a growth-associated type, and comprised up to 40 % of the total cellular protein. The maximum specific activity in the transformant was 208 U/mg protein which was approximately 16 times higher than in L. casei or in the previously constructed Escherichia coil transformant.

Mutants of Bacillus subtilis constitutive for L-leucine dehydrogenase synthesis were selected. Using these mutants we could determine two functional roles for the L-leucine dehydrogenase. This enzyme liberates ammonium ions from branched chain amino acids when supplied as the sole nitrogen source. A
