中文摘要
我们打算获得更详细的信息,对实际的氧化还原
光系统II的Mn-簇的状态,在不同的S-状态,
通过Mn K边XANES。 两组XANES数据
目前可用的OEC中的闪光引起的变化(由两个
不同的群体,在两种不同的准备)不同意
在锰的参与的一些基本方面,
在各种S态转变中的氧化。 我们的目标是
对不同类型的样品进行XANES实验,但是
在其他条件相同的情况下,通过与
另一组。 这将使我们能够解决现有的
在不同的锰氧化还原化学参与的差异
S-状态转换,这对于理解
光合水氧化机制。
英文摘要
We intend to acquire more detailed information on the actual redox
states of the Mn-cluster of Photosystem II, in the different S-states,
by way of Mn K-edge XANES. The two sets of XANES data on
flash-induced changes in the OEC presently available (performed by two
different groups, on two different kinds of preparations) do not agree
with each other in some essential aspects of the involvement of Mn
oxidation in the various S-state transitions. It is our specific aim
to perform XANES experiments on the different types of samples, but
under otherwise identical conditions, by a collaborative effort with
the other group. This should enable us to settle the existing
discrepancy on the involvement of Mn-redox chemistry in the different
S-state transitions, which will be essential for understanding the
mechanism of photosynthetic water oxidation.
