On methylamine assimilation in a bacterium
Archiv f�r Mikrobiologie, 1967Kinetic analyses of 14C-methylamine and 14C-bicarbonate assimilation in a gram-negative diplococcus suggests that methylamine assimilation occurs via a glycine-serine hydroxymethylation sequence rather than autotrophically by a Calvin cycle.

Methylamine is the simplest aliphatic amine found in human urine. In the body it is thought to play a significant part in central nervous system disturbances observed during renal and hepatic disease and also has a role in general toxicity caused by oxidative stress.

The photolysis of methylamine has been shown to proceed essentially by two consecutive first-order reactions, the first to produce hydrogen, ammonia, and CH2 : NCH3; the second a dehydrogenation of the latter at a rate approximately double the first. A mechanism involving hydrogen atoms has been postulated.

Enzymology of Methylamine Dehydrogenase
1996Methylamine dehydrogenase (MADH) belongs to the class of quinoprotein enzymes because it has tryptophyl tryptophanquinone (TTQ) as cofactor. In most cases, it is clear that the small blue copper protein, amicyanin, functions as natural electron acceptor.

Methylamine metabolism in a pseudomonas species
Archives of Biochemistry and Biophysics, 1972Abstract The mechanism by which a nonphotosynthetic bacterium Pseudomonas sp. (Shaw Strain MA) grows on the one-carbon source, methylamine, was investigated by comparing enzyme levels of cells grown on methylamine, to cells grown on acetate or succinate.

Microwave Spectrum of Methylamine (I)
Journal of the Physical Society of Japan, 1953Microwave spectrum of methylamine molecule has been studied in the frequency range between 7 and 30 kMc/sec. More than two hundred lines and their Stark effects have been measured. These lines are divided into three kinds: (1) Δ J =0, Δ K =±1, (2) Δ J =±1, \(\varDelta K{=}{\mp}1\), and (3) Δ J =0, Δ K =0.

Electrochemical Oxidation of Methane to Methylamine
Journal of the American Chemical SocietyThe electrochemical methane (CH4) oxidation reaction under ambient conditions is a promising approach for natural gas utilization. However, the highly stable nature of CH4 restrains efficient cleavage of the C-H bond without overoxidation. To this end, we proposed a coupled oxidative strategy for converting CH4 to value-added products via NH2 ...

Methylamination of some 3-nitro-1,5-naphthyridines with liquid methylamine
Journal of Heterocyclic Chemistry, 20063-Nitro-1,5-naphthyridine and its 2-substituted derivatives (1a-f) are dehydro-methylaminated with a solution of potassium permanganate in liquid methylamine (LMA-PP) to the corresponding 4-methylamino-3-nitro-1,5- naphthyridines (3a-e). The intermediary 4-methylamino σ adducts of 2-R-3-nitro-1,5-naphthyridines (R = H, NH2, Cl, NHCH3, OC2H5, OH) (2a-f)
