Comparison of the structural genes for pyruvate decarboxylase in different Zymomonas mobilis strains

The nucleotide sequence of the pyruvate decarboxylase gene from Zymomonas mobilis ATCC 29191 was determined and compared with the sequence of the corresponding gene in Z. mobilis ATCC 31821. Differences were found, leading to variations on the amino acid level and to different sites for restriction endonucleases.
