Fourier transform infrared spectrum of the secondary quinone electron acceptor Q(B) in photosystem II.
Suzuki H, Nagasaka MA, Sugiura M, Noguchi T. Suzuki H, et al. Biochemistry. 2005 Aug 30;44(34):11323-8. doi: 10.1021/bi051237g. Biochemistry. 2005. PMID: 16114869
The Q(B)(-)/Q(B) difference spectrum exhibited a strong C...O stretching band of the semiquinone anion at 1480 cm(-)(1), the frequency higher by 2 cm(-)(1) than that of the corresponding band of Q(A)(-), in agreement with the previous S(2)Q(B)(-)/S(1)Q(B) spectrum of the PSII mem …

Photo-oxidation of tyrosine in a bio-engineered bacterioferritin 'reaction centre'-a protein model for artificial photosynthesis.
Hingorani K, Pace R, Whitney S, Murray JW, Smith P, Cheah MH, Wydrzynski T, Hillier W. Hingorani K, et al. Biochim Biophys Acta. 2014 Oct;1837(10):1821-34. doi: 10.1016/j.bbabio.2014.07.019. Epub 2014 Aug 5. Biochim Biophys Acta. 2014. PMID: 25107631 Free article.
High-resolution (2.1A) crystal structures of the tyrosine variants show that there are no mutation-induced effects on the overall 3-D structure of the protein. Small effects are observed in the Y45F variant. ...

Amino acid deletions in the cytosolic domains of the chlorophyll a-binding protein CP47 slow Q(A)- oxidation and/or prevent the assembly of photosystem II.
Clarke SM, Funk C, Hendry GS, Shand JA, Wydrzynski T, Eaton-Rye JJ. Clarke SM, et al. Plant Mol Biol. 2002 Oct;50(3):563-72. doi: 10.1023/a:1019865909130. Plant Mol Biol. 2002. PMID: 12369631
To identify important hydrophilic cytosolic regions, oligonucleotide-directed mutagenesis was employed to introduce short segment deletions into loops B and D, and the C-terminal domain. Four strains carrying deletions of between three and five residues were created in loo …

Conversion of the Escherichia coli cytochrome b562 to an archetype cytochrome b: a mutant with bis-histidine ligation of heme iron.
Hay S, Wydrzynski T. Hay S, et al. Biochemistry. 2005 Jan 11;44(1):431-9. doi: 10.1021/bi0492298. Biochemistry. 2005. PMID: 15628885
While the H63N mutation has no measurable effect on the cytochrome, the M7H mutation converts the atypical His/Met heme ligation in cytochrome b(562) to the classic cytochrome b-type bis-His ligation. This mutation has little effect on the K(d) of heme binding but signific …
