Low-Spin Heme b3 in the Catalytic Center of Nitric Oxide Reductase from Pseudom...
Timóteo, Cristina G.; Pereira, Alice S.; Martins, Carlos E.; Naik, Sunil G.; Duarte, Américo G.; Moura, José J. G.; Tavares, Pedro; Moura, IsabelBiochemistry, 2011, 50 (20), pp 4251–4262 DOI: 10.1021/bi101605p ; Respiratory nitric oxide reductase (NOR) was purified from membrane extract of Pseudomonas (Ps.) nautica cells to homogeneity as judged by polyacrylamide gel electrophoresis. The purified protein is a heterodimer with subunits of molecular masses of 54 and 18 kDa. The gene encoding both subunits was cloned and sequenced. The amino acid sequence...

Najmudin, Shabir; Bonifácio, Cecília; Duarte, Américo G.; Pualeta, Sofia R.; Moura, Isabel; Moura, José J. G.; Romão, Maria J.Acta Crystallographica Section F Structural Biology and Crystallization Communications Volume 65, Part 8 ; The orange-coloured protein (ORP) from Desulfovibrio gigas is a 12 kDa protein that contains a novel mixed-metal sulfide cluster of the type [S2MoS2-CuS2MoS2]. Diffracting crystals of the apo form of ORP have been obtained. Data have been collected for the apo form of ORP to 2.25 A ° resolution in-house a...
NMR assignment of the apo-form of a Desulfovibrio gigas protein containing a no...
Pauleta, Sofia R.; Duarte, Américo G; Carepo, Marta S.; Pereira, Alice S.; Tavares, Pedro; Moura, Isabel; Moura, José J. G.Biomol NMR Assign (2007) 1:81–83 DOI 10.1007/s12104-007-9022-3 ; We report the 98% assignment of the apo-form of an orange protein, containing a novel Mo–Cu cluster isolated from Desulfovibrio gigas. This protein presents a region where backbone amide protons exchange fast with bulk solvent becoming undetectable. These residues were assigned using 13C-detection experiments.
