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.This publication has 14 references indexed in Scilit:
