Microperoxidase
INTRODUCTION This communication is a report on some physical and chemical properties of MP and on a striking difference between the distribution of MP and that of HRP when the two substances are administered to mice . In particular, MP penetrates into an extracellular compartment from which HRP is largely excluded . This finding is consistent with the smaller molecular size of MP and suggests t...
متن کاملTotally synthetic medium for susceptibility testing.
The results of disk diffusion and plate dilution susceptibility testing of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis on media gelled with agar-agar or with a synthetic hydrogel were compared. Synthetic hydrogel can be combined with a totally defined synthetic amino acid medium to yield a reproducible, totally defined, synthetic solid medium without t...
متن کاملThe effect of solvent on the catalytic properties of microperoxidase-11.
The effect of a range of solvents on the catalytic oxidation of methyl phenyl sulfide to methyl phenyl sulfoxide by MP-11 and by a cyclodextrin derivative of MP-11 was examined. The addition of low concentrations of alcohols enhanced the initial rate of sulfoxidation, most likely due to dispersion of MP-11 aggregates. Higher alcohol concentrations resulted in a decrease in activity arising from...
متن کاملHydrogen peroxide biosensor based on microperoxidase-11 entrapped in lipid membrane.
A highly catalytic activity microperoxidase-11 (MP-11) biosensor for H(2)O(2) was developed to immobilizing the heme peptide in didodecyldimethylammonium bromide (DDAB) lipid membrane. The enzyme electrode thus obtained responded to H(2)O(2) without electron mediator or promoter, at a potential of +0.10 V versus Agmid R:AgCl. A linear calibration curve is obtained over the range from 2.0 x 10(-...
متن کاملReactions of persulfides with the heme cofactor of oxidized myoglobin and microperoxidase 11: reduction or coordination.
Persulfides of cysteine (CysSSH), glutathione (GSSH) or N-methoxycarbonyl-penicillamine (NAcPenSSH) react with the ferric form of myoglobin (metMb(iii)) to yield the oxy-ferrous (oxyMb(ii)) or deoxy-ferrous (deoxyMb(ii)) forms of myoglobin under aerobic or anaerobic conditions, respectively. Under aerobic conditions, CysSSH and NAcPenSSH react with the hypervalent form of myoglobin (ferrylMb(iv...
