The nickel/iron/sulfur center of the carbon monoxide dehydrogenase (carbon monoxide:(acceptor)oxidoreductase; EC 1.2.99.2) enzyme from Rhodospirillum rubrum (Rr-CODH) was studied by x-ray absorption...

Applications of synchrotron radiation to protein crystallography: preliminary results.

Phillips, J C, Wlodawer, A, Yevitz, M M, Hodgson, K O

X-ray diffraction photographs of protein single crystals have been obtained using synchrotron radiation produced by an electron-positron storage ring. The diffracted intensities observed with this...

X-ray absorption spectroscopy of the dimeric iron site in azidomethemerythrin from Phascolopsis gouldii.

Hendrickson, W A, Co, M S, Smith, J L, Hodgson, K O, Klippenstein, G L

X-ray absorption spectroscopy has been used to study the dimeric iron center in azidomethemerythrin from Phascolopsis gouldii. Absorption edge data confirm that the two iron atoms are present as...

White lines in L-edge x-ray absorption spectra and their implications for anomalous diffraction studies of biological materials.

Lye, R C, Phillips, J C, Kaplan, D, Doniach, S, Hodgson, K O

We have measured high-resolution x-ray absorption spectra of lanthanide (Ln) and heavy transition metal complexes that display prominent narrow absorption peaks near the L2 and L3 absorption edges....

[4Fe-4S]-cluster-depleted Azotobacter vinelandii ferredoxin I: a new 3Fe iron-sulfur protein.
