Aldoxime dehydratase: Probing the heme environment involved in the synthesis of the carbon-nitrogen triple bond
Pinakoulaki, Eftychia; Koutsoupakis, Constantinos; Sawai, H.; Pavlou, A.; Kato, Y.; Asano, Y.; Aono, S. (2011)Fourier transform infrared (FTIR) spectra, "light" minus "dark" difference FTIR spectra, and time-resolved step-scan (TRS 2) FTIR spectra are reported for carbonmonoxy aldoxime dehydratase. Two C-O modes of heme at 1945 ...

Evidence for the presence of two conformations of the heme a 3-CuB pocket of cytochrome caa 3 from Thermus thermophilus
Pavlou, A.; Soulimane, T.; Pinakoulaki, Eftychia (2011)Resonance Raman (RR) and "light" minus "dark" Fourier transform infrared (FTIR) difference spectra are reported for the CO-bound caa3 oxidase from Thermus thermophilus. Two Fe-CO stretching modes at 518 and 507 cm-1, the ...

Probing the ligand recognition and discrimination environment of the globin-coupled oxygen sensor protein YddV by FTIR and time-resolved step-scan FTIR spectroscopy
Pavlou, A.; Martínková, M.; Shimizu, T.; Kitanishi, K.; Stranava, M.; Loullis, Andreas; Pinakoulaki, Eftychia (2015)YddV is a newly discovered signal transducer heme protein that recognizes O2 and CO. Structural differences in the ligand-bound heme complex in YddV reflect variations in catalytic regulation by O2 and CO. Time-resolved ...
