Nucleotide sequence of the Bacillus subtilis xylose isomerase gene: extensive homology between the Bacillus and Escherichia coli enzyme.
نویسندگان
چکیده
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.

The xylose isomerase gene from the thermophile Clostridium thermohydrosulfuricum has been cloned, using a fragment of the Bacillus subtilis gene as a probe. The complete nucleotide sequence of the gene was analyzed. C. thermohydrosulfuricum is the most thermophilic organism from which a xylose isomerase gene has been cloned and characterized. Comparison with amino acid sequences from other xylo...
متن کاملIdentification of essential histidine residues in the active site of Escherichia coli xylose (glucose) isomerase.
Two conserved histidine residues (His-101 and His-271) appear to be essential components in the active site of the enzyme xylose (glucose) isomerase (EC 5.3.1.5). These amino acid residues were targeted for mutagenesis on the basis of sequence homology among xylose isomerases isolated from Escherichia coli, Bacillus subtilis, Ampullariella sp. strain 3876, and Streptomyces violaceus-niger. Each...

The Bacillus subtilis rpoD gene has been sequenced and the primary structure of its product deduced. The molecular weight calculated for the sigma 43 is 42,828. The DNA and protein sequences of sigma 43 exhibit extensive homology to the Escherichia coli rpoD gene and its sigma 70 product, especially in the C-terminal two-thirds of the sequence. Other proteins exhibiting partial homology with si...

The Bacillus subtilis pss gene encoding phosphatidylserine synthase was cloned by its complementation of the temperature sensitivity of an Escherichia coli pssA1 mutant. Nucleotide sequencing of the clone indicated that the pss gene encodes a polypeptide of 177 amino acid residues (deduced molecular weight of 19,613). This value agreed with the molecular weight of approximately 18,000 observed ...
