Abstract
A quinone was extracted and purified from the cells of an extremely thermophilic hydrogen bacterium, Hydrogenobacter thermophilus TK-6 (IAM 12695). Its chemical structure was determined as 2-methylthio-3-VI, VII-tetrahydromultiprenyl-1,4-naphthoquinone by elemental analysis, 1H nuclear magnetic resonance spectroscopy, mass spectroscopy, and infrared spectroscopy of the quinone and by gas-liquid chromatography and gas chromatography-mass spectroscopy analysis of the ozonolysis products of the quinone. It was shown that the other five strains of H. thermophilus have the same quinone system. We named the quinone with the 2-methylthio-1,4-naphthoquinone nucleus "methionaquinone." The abbreviation of MTK is recommended for this class of quinone.
摘要
从嗜热氢细菌嗜热栖热菌TK-6（IAM 12695）的细胞中提取并纯化出一种醌。通过对该醌进行元素分析、¹H核磁共振光谱、质谱、红外光谱，以及对该醌的臭氧分解产物进行气液色谱和气相色谱-质谱分析，确定其化学结构为2-甲硫基-3-VI，VII-四氢多异戊二烯基-1,4-萘醌。结果表明，嗜热栖热菌的其他五株菌株具有相同的醌系统。我们将具有2-甲硫基-1,4-萘醌核的醌命名为“甲硫萘醌”。建议将这类醌简称为MTK。
