BIIbmdARY t a r r 7 a'j';QI 7 1`he peroxidative system involving hepatic catalase plays a major role in t e dation of 6 i c el a /^ ` i methanol in the rat (1), but in the monkey the peroxidative mechanism does not appear to ^0, J be important. This conclusion is based on the following observations: (a) ethanol and °r y methanol were about equally reactive with the peroxidative system, but etha...

Methanol dehydrogenase has been purified from the type I marine methanotroph Methylomonas sp. strain A4 and found to be similar to other methanol dehydrogenase enzymes in subunit composition, molecular mass, and N-terminal sequence of the two subunits. A heterologous gene probe and a homologous oligonucleotide have been used to identify a DNA fragment from Methylomonas sp. strain A4 which conta...

Methanol poisoning is an uncommon but an extremely hazardous intoxication. Since methanol is a versatile fuel and is having increasing usage in an energy-conscious society, a high index of suspicion and swift laboratory confirmation is essential in managing this poisoning. Methanol poisoning may occur in sporadic or epidemic circumstances. Chronic exposure may occur in the occupational setting....

in the urine, and the kidney must have a considerable power of concentrating formate. The inhibition of the appearance of formate during the administration ofethanol is in accordance with Zatman's (1946) interpretation of the earlier experiments, namely, that a primary oxidation of methanol to formaldehyde through the agency of alcohol dehydrogenase is competitively inhibited by ethanol. More r...

UNLABELLED Many methylotrophic taxa harbor two distinct methanol dehydrogenase (MDH) systems for oxidizing methanol to formaldehyde: the well-studied calcium-dependent MxaFI type and the more recently discovered lanthanide-containing XoxF type. MxaFI has traditionally been accepted as the major functional MDH in bacteria that contain both enzymes. However, in this study, we present evidence tha...

When grown on methylamine as a sole carbon source, Paracoccus denitrificans synthesizes a Type I blue copper protein which mediates electron transfer between methylamine dehydrogenase and cytochrome c. This blue copper protein does not serve as an electron acceptor for methanol dehydrogenase and is not synthesized by cells grown on methanol or succinate. The blue copper protein and methylamine ...

Background: Methanol is regarded as a biorenewable platform feedstock because nearly all bioresources can be converted into methanol through syngas. Biological conversion of methanol using synthetic methylotrophs has thus gained worldwide attention. Results: Herein, to endow Escherichia coli with the ability to utilize methanol, an artificial linear methanol assimilation pathway was assembled i...
