Actinomycetes secrete into their surroundings a suite of enzymes involved in the biodegradation of plant lignocellulose; these have been reported to include both hydrolytic and oxidative enzymes, including peroxidases. Reports of secreted peroxidases have been based upon observations of peroxidase-like activity associated with fractions that exhibit optical… (More)
The C-terminal fragment of the internal 110-kilodalton passenger domain of the Hap protein of nontypeable Haemophilus influenzae is a potential vaccine candidateThe C-terminal fragment of the internal 110-kilodalton passenger domain of the Hap protein of nontypeable Haemophilus influenzae is a potential vaccine candidate.
initial preparation, the Department of Health formed and consulted with a School Indoor Air Quality Advisory Committee, which provided valuable technical guidance and policy support. The Department of Health encourages all users of the Manual to examine the concepts, recommendations, and procedures outlined in the Manual; evaluate their usefulness and… (More)
We re-determined the near infrared (NIR) spectral signatures (650-980nm) of the different cytochrome c oxidase redox centres, in the process separating them into their component species. We confirm that the primary contributor to the oxidase NIR spectrum between 700 and 980nm is cupric CuA, which in the beef heart enzyme has a maximum at 835nm. The 655nm… (More)
We previously reported that high micromolar concentrations of nitric oxide were able to oxidize mitochondrial cytochrome c at physiological pH, producing nitroxyl anion (Sharpe and Cooper, 1998 Biochem. J. 332, 9-19). However, the subsequent re-evaluation of the redox potential of the NO/NO(-) couple suggests that this reaction is thermodynamically… (More)
Cryptochromes (crys) are flavoprotein photoreceptors present throughout the biological kingdom that play important roles in plant development and entrainment of the circadian clock in several organisms. Crys non-covalently bind flavin adenine dinucleotide (FAD) which undergoes photoreduction from the oxidised state to a radical form suggested to be active… (More)
This essay foeuses on the list of 1983 " chemistry " papers most cited from 1983 to 1985 in the Science CitufiorI Irufe.r " (SCF) (see the Bibliography). This is the fourth group of highly cited chemistry papers that we have analyzed since 1983, when we examined papers published in 1980.1 Methodology Once again the task of classifying the chemistry papers… (More)
