Enzymes inactivating the chemoattractants folic acid and pterin were detected in extracellular, intracellular, and particulate fractions obtained from Dictyostelium discoideum strains NC4 and AX-2 and Polysphondylium violaceum. The products of the inactivation reaction were analyzed by thin-layer chromatography and UV spectroscopy. Results obtained indicate that folic acid and pterin were deaminated to 2-deamino folic acid and lumazine, respectively.
在从盘基网柄菌NC4和AX - 2菌株以及紫多头绒泡菌中获得的细胞外、细胞内和颗粒组分中检测到了使趋化因子叶酸和蝶呤失活的酶。通过薄层色谱法和紫外光谱法分析了失活反应的产物。所得结果表明,叶酸和蝶呤分别被脱氨基生成2 - 脱氨基叶酸和核黄素。
