Biochemistry, 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...
Objetivou-se, com o presente trabalho, avaliar a produtividade de matéria seca de seis gramíneas, sob efeito de diferentes lâminas de irrigação, em diferentes estações do ano. O experimento foi conduzido em esquema de parcelas subsubdivididas havendo, nas parcelas seis gramíneas (Xaraés, Mombaça, Tanzânia, Pioneiro, Marandu e Estrela), nas subparcelas, seis lâminas de irrigação (0, 18, 45, 77, 100 e 120% da ref...
Protein Sci. 2009 Mar;18(3):619-28. doi: 10.1002/pro.69. ; Nitric Oxide Reductase (NOR) is an integral membrane protein performing the reduction of NO to N2O. NOR is composed of two subunits: the large one (NorB) is a bundle of 12 transmembrane helices (TMH). It contains a b type heme and a binuclear iron site, which is believed to be the catalytic site, comprising a heme b and a non-hemic iron. The small subu...
