The Production of Methemoglobin by Pneumococci [PDF]
Journal of Experimental Medicine, 1914 1. Pneumococci in contact with hemoglobin transform this into methemoglobin. This reaction occurs only when the pneumococci are living; it is not induced by the culture fluid or by extracts of the bacteria. 2. The reaction does not occur when hemoglobin is added to an emulsion of washed pneumococci in salt solution.

Carboxyhemoglobin and Methemoglobin in Asthma [PDF]
Lung, 2015 Nitric oxide (NO) and carbon monoxide (CO) are synthesized at high levels in asthmatic airways. NO can oxidize hemoglobin (Hb) to methemoglobin (MetHb). CO binds to heme to produce carboxyhemoglobin (COHb). We hypothesized that MetHb and COHb may be increased in asthma.

Interactions of Solvent with the Heme Region of Methemoglobin and Fluoro-Methemoglobin
Biophysical Journal, 1981 It is now more than 20 years since Davidson and collaborators (1957, Biochim. Biophys, Acta. 26:370-373; J. Mol. Biol. 1:190-191) applied the theoretical ideas of Bloembergen et al. (1948. Phys. Rev. 73:679-712) on outer sphere magnetic relaxation of solvent protons to studies of solutions of methemoglobin. From then on, there has been debate regarding

Blood, 1963 Abstract 1. It has been shown that mixtures of normal and G-6-PD deficient nitrite-treated erythrocytes reduced methemoglobin at a rate considerably more rapid than that computed from their individual rates of methemoglobin reduction. 2.

Notes on Methemoglobin Determination
Clinical Chemistry, 1960 Abstract The Evelyn-Malloy procedure for the determination of methemoglobin in blood has been modified for use with a Coleman Jr. spectrophotometer by using a lower dilution of blood to reduce the effective instrument error from a possible 10 per cent to a possible 3 per cent.

Species Comparison of Methemoglobin Reductase
Experimental Biology and Medicine, 2003 Methemoglobin (MHb) formation is effective in treating cyanide (CN) poisoning. Endogenous activity of the enzyme MHb reductase (MR) reflects the capacity to reduce MHb and thus represents a key factor for evaluating anti-CN efficacy of MHb formers. MR activity was measured in whole blood of nine animal species and was compared with human MR activity ...

Properties of methemoglobin reductase and kinetic study of methemoglobin reduction.
Journal of Biological Chemistry, 1981 A soluble erythrocyte cytochrome b5 was purified as the substrate of methemoglobin reductase and an electron carrier to methemoglobin. The isoelectric point of this protein was at pH 4.3, and E0' was -0.010 at pH 7.0.. The Km value of the enzyme for this protein was 1 x 10(-4) M, and the turnover number (k5) was 3.4 x 10(4) min-1, with NADH as an ...
