Abstract
The sucrose phosphorylase gene of an isolate, Leuconostoc mesenteroides No. 165, was amplified by PCR, cloned on pUC118, and expressed in E. coli. The nucleotide sequence of the gene showed 96.3% similarity to that of L. mesenteroides ATCC12291 and 67% to that of Streptococcus mutans, but low similarity to the Agrobacterium vitis gene. The cloned gene, which fusing with lacZα, was expressed inducibly with IPTG in E. coli to produce an active enzyme in large quantities that accounted for aboiit 50% of the total cell protein.
