Coupling of helix E-F motion with the O-nitrito and 2-nitrovinyl coordination in myoglobin
Ioannou, Androulla; Lambrou, Alexandra; Daskalakis, Vangelis; Pinakoulaki, Eftychia (2017)Myoglobin (Mb) is known to react slowly with nitirite to form the green pigment by NO2 − cordination to the heme Fe in the O-binding nitrito (O1[sbnd]N[dbnd]O2) mode and to the heme 2-vinyl position. Nitrite is a powerful ...

Nitrite coordination in myoglobin
Ioannou, Androulla; Lambrou, Alexandra; Daskalakis, Vangelis; Pinakoulaki, Eftychia (2017)The coordination of nitrite in myoglobin (Mb) has been characterized by resonance Raman spectroscopy and the frequencies of the nitrite bound to the heme Fe as well to the 2-vinyl have been computed by density functional ...

Resonance Raman detection of the myoglobin nitrito heme Fe-O-N=O/2-nitrovinyl species: Implications for helix E-helix F interactions
Lambrou, Alexandra; Pinakoulaki, Eftychia (2015)The description of biological activity in heme proteins responsible for activating small molecules requires identification of ligand movement into the metal and non-metal binding sites. Mechanisms of nitrite reductase ...

Spin Crossover in Nitrito-Myoglobin as Revealed by Resonance Raman Spectroscopy
Lambrou, Alexandra; Ioannou, Androulla; Pinakoulaki, Eftychia (2016)The myoglobin (Mb) heme Fe-O-N=O and heme Fe-O-N=O/2-nitrovinyl species have been characterized by resonance Raman spectroscopy. In the heme Fe-O-N=O species, the bound nitrite ligand is removed by solvent exchange, thus ...
