Anaerobic catabolism of amino acids may have provided the main source of energy for primitive microorganisms. Examples are given of amino acid catabolic reactions coupled to substrate level phosphorylations occurring in present-day anaerobes which may be biochemical fossils from a very early stage of the evolution of procaryotes.
氨基酸的无氧分解代谢可能为原始微生物提供了主要能量来源。文中列举了一些与当今厌氧菌中发生的底物水平磷酸化相偶联的氨基酸分解代谢反应实例,这些厌氧菌可能是原核生物进化早期阶段的生化化石。
