Abstract
Operation of the dissimilatory hexulose phosphate cycle of formaldehyde oxidation in Pseudomonas oleovarans has been directly confirmed. Extracts of this typical facultative methylotroph catalyze the formation of 14CO2 from 14C-formaldehyde. The process depends on the presence of ribose-5-phosphate, NADP or NAD, and is linear in time. Oxidation of formaldehyde via formate to CO2 is of a minor importance in the energy metabolism of the methylotroph.
摘要
在食油假单胞菌中，甲醛氧化异化磷酸己酮糖循环的运作已得到直接证实。这种典型兼性甲基营养菌的提取物能催化从¹⁴C-甲醛生成¹⁴CO₂。该过程依赖于5-磷酸核糖、NADP或NAD的存在，且在时间上呈线性关系。在甲基营养菌的能量代谢中，甲醛经甲酸氧化为CO₂的过程重要性较低。
