Dynamics of nitric oxide in the active site of reduced cytochrome c oxidase aa3.
Vos MH, Lipowski G, Lambry JC, Martin JL, Liebl U. Vos MH, et al. Among authors: liebl u. Biochemistry. 2001 Jul 3;40(26):7806-11. doi: 10.1021/bi010060x. Biochemistry. 2001. PMID: 11425307
The formation of the product state--the unliganded heme a3 ground state--occurs in a similar stepwise manner (period approximately 700 fs) as previously observed for carbon monoxide photolysis from this enzyme and interpreted in terms of ballistic ligand motions in the active sit …

Interactions between heme d and heme b595 in quinol oxidase bd from Escherichia coli: a photoselection study using femtosecond spectroscopy.
Borisov VB, Liebl U, Rappaport F, Martin JL, Zhang J, Gennis RB, Konstantinov AA, Vos MH. Borisov VB, et al. Among authors: liebl u. Biochemistry. 2002 Feb 5;41(5):1654-62. doi: 10.1021/bi0158019. Biochemistry. 2002. PMID: 11814360 Free article.
Substantial polarization effects, unprecedented for optical studies of heme proteins, were observed in the CO photodissociation spectra, implying interactions between heme d (the chlorin ligand binding site) and the close-lying heme b(595) on the picosecond time scale; this gener …

Ligand binding dynamics to the heme domain of the oxygen sensor Dos from Escherichia coli.
Liebl U, Bouzhir-Sima L, Kiger L, Marden MC, Lambry JC, Négrerie M, Vos MH. Liebl U, et al. Biochemistry. 2003 Jun 3;42(21):6527-35. doi: 10.1021/bi027359f. Biochemistry. 2003. PMID: 12767236
This is somewhat slower than recombination of the external ligands NO, with which picosecond rebinding occurs with unprecedented efficiency (>99%) with a predominant phase of approximately 5 ps, and O(2) (97% in 5 ps, Liebl, U., Bouzhir-Sima, L., Negrerie, M., Ma …
