Abstract
Reaction of O2 and CO with a caa3-type terminal cytochrome oxidase (EC 1.9.3.1) from the thermophilic bacterium PS3 grown with high aeration was studied at low temperatures. The CO recombination at the temperature range studied (-50 degrees C to -80 degrees C) followed first-order kinetics with an activation energy of 29.3 kJ/mol (7.0 kcal/mol). In the presence of O2 at -113 degrees C the photolysed reduced form binds O2 to form an 'oxy' intermediate similar to Compound A. At a higher temperature (-97 degrees C) another intermediate, similar to Compound B, is formed as a result of electron transfer from the enzyme to the liganded O2.
摘要
在低温下研究了氧气（O₂）和一氧化碳（CO）与在高通气条件下培养的嗜热细菌PS3的caa₃型末端细胞色素氧化酶（EC 1.9.3.1）的反应。在所研究的温度范围（-50℃至-80℃）内，CO重组遵循一级动力学，活化能为29.3千焦/摩尔（7.0千卡/摩尔）。在-113℃有O₂存在时，光解还原形式结合O₂形成类似于化合物A的“氧合”中间体。在较高温度（-97℃）下，由于电子从酶转移到配位的O₂，会形成另一种类似于化合物B的中间体。
