Glutamine:fructose-6-phosphate amidotransferase (GFAT) is the rate-limiting enzyme in hexosamine synthesis and has been implicated in the control of growth factor gene expression. We cloned a mouse cDNA which is 91% homologous to the human sequence. The deduced amino-acid sequence shows 98.6% identity to human GFAT. The cDNA is derived from a 7-kb mRNA in the mouse, while there are multiple-sized human mRNAs.
果糖-6-磷酸酰胺转移酶(GFAT)是己糖胺合成中的限速酶,并且与生长因子基因表达的调控有关。我们克隆了一个与人类序列有91%同源性的小鼠cDNA。推导的氨基酸序列与人类GFAT有98.6%的同一性。该cDNA源自小鼠中的一个7kb mRNA,而人类有多种大小的mRNA。
