S(-3) state of the water oxidase in photosystem II.
Messinger J, Seaton G, Wydrzynski T, Wacker U, Renger G. Messinger J, et al. Among authors: wydrzynski t. Biochemistry. 1997 Jun 10;36(23):6862-73. doi: 10.1021/bi962653r. Biochemistry. 1997. PMID: 9188681
Kinetic determination of the fast exchanging substrate water molecule in the S3 state of photosystem II.
Hillier W, Messinger J, Wydrzynski T. Hillier W, et al. Among authors: wydrzynski t. Biochemistry. 1998 Dec 1;37(48):16908-14. doi: 10.1021/bi980756z. Biochemistry. 1998. PMID: 9836583
In a previous communication we showed from rapid isotopic exchange measurements that the exchangeability of the substrate water at the water oxidation catalytic site in the S3 state undergoes biphasic kinetics although the fast phase could not be fully resolved at that time [Mess …

(18)O isotope exchange measurements reveal that calcium is involved in the binding of one substrate-water molecule to the oxygen-evolving complex in photosystem II.
Hendry G, Wydrzynski T. Hendry G, et al. Among authors: wydrzynski t. Biochemistry. 2003 May 27;42(20):6209-17. doi: 10.1021/bi034279i. Biochemistry. 2003. PMID: 12755624
Previous rapid (millisecond range) (18)O isotope exchange measurements between added H(2)(18)O and the photogenerated O(2) have shown that the two substrate-water molecules bind to separate sites throughout the S-state cycle, as revealed by their kinetically distinct rates of (18 …

The two substrate-water molecules are already bound to the oxygen-evolving complex in the S2 state of photosystem II.
Hendry G, Wydrzynski T. Hendry G, et al. Among authors: wydrzynski t. Biochemistry. 2002 Nov 5;41(44):13328-34. doi: 10.1021/bi026246t. Biochemistry. 2002. PMID: 12403635
The unresolvable fast phase has left open the possibility that the second substrate-water molecule binds to the catalytic site only after the formation of the S(3) state [Hillier, W., and Wydrzynski, T. (2000) Biochemistry 39, 4399-4405]. However, for PSII samples d …
