Filaments of the blue-green alga Anabaena variabilis permeabilized by dimethylsulfoxide (DMSO) produce increased amounts of 5-aminolevulinate in the presence of levulinic acid. The metabolic activity of the filaments remains unperturbed in the presence of up to 7.5% (v/v) DMSO. Studies utilizing DMSO-permeabilized filaments confirm that 5-aminolevulinate is synthesized preferably from glutamate and, to a lesser extent, from alpha-ketoglutarate in this organism.
经二甲基亚砜(DMSO)渗透处理的蓝绿藻鱼腥藻丝体在存在乙酰丙酸的情况下会产生更多的 5-氨基乙酰丙酸。在高达 7.5%(v/v)DMSO 的存在下,丝体的代谢活性保持未受干扰。利用 DMSO 渗透处理的丝体制备研究证实,5-氨基乙酰丙酸在该生物中主要由谷氨酸合成,其次由α-酮戊二酸合成。
