Nucleotide sequence of the Bacillus subtilis xylose isomerase gene: extensive homology between the Bacillus and Escherichia coli enzyme.
The xylose isomerase gene from Bacillus subtilis was cloned from a genomic BamH1 library by complementation of an isomerase defective Escherichia coli strain as previously described. The ATG initiation codon is preceded by a Shine-Dalgarno sequence and two hexamers being characteristic for the promoter region of Bacillus genes. The structural gene consists of 1320 base pairs, thus coding for a polypeptide chain of 440 amino acids with a molecular weight of 49 680. The polypeptide primary structure shows over 50% homology to that of the E. coli xylose isomerase.
