We have recently succeeded in measuring the first L-edge spectra of Mn metalloproteins. These measurements require a Parylene filter to selectively absorb the large amount of oxygen fluorescence in protein samples. The higher resolution of L-edges should help greatly toward understanding the catalytic cycles of Mn enzymes such as the oxygen-evolving complex in Photosystem II and Mn catalase.

我们最近成功测量了第一个 L 边缘光谱 锰金属蛋白。 这些测量需要聚对二甲苯过滤器 选择性地吸收大量的氧荧光 蛋白质样品。 L 边缘的更高分辨率应该会有很大帮助 有助于了解锰酶的催化循环，例如 光系统 II 和锰过氧化氢酶中的放氧复合物。
