We have sequenced the complete sor-operon of Klebsiella pneumoniae KAY2026. The operon has been mapped at 91 min on the Klebsiella gene-map. It comprises seven open reading frames for the genes sorCDFBAME, which are expressed from the single promotor sorCP. The gene sorC codes for a regulator protein that positively and negatively regulates the expression of the operon; sorD encodes a D-glucitol-6-phosphate dehydrogenase, the genes sorFBAM encode four proteins of a phosphoenolpyruvate-dependent L-sorbose-phosphotransferase system and sorE, finally, an L-sorbose-1-phosphate-reductase.
我们已对肺炎克雷伯菌KAY2026的完整sor操纵子进行了测序。该操纵子已定位在克雷伯菌基因图谱的91分钟处。它包含用于sorCDFBAME基因的七个开放阅读框，这些基因由单一启动子sorCP表达。基因sorC编码一种调节蛋白，该蛋白对操纵子的表达进行正向和负向调节；sorD编码一种D-葡萄糖醇-6-磷酸脱氢酶，基因sorFBAM编码磷酸烯醇丙酮酸依赖性L-山梨糖磷酸转移酶系统的四种蛋白质，最后，sorE编码一种L-山梨糖-1-磷酸还原酶。
