Methylamine uptake in Pseudomonas species strain MA: utilization of methylamine as the sole nitrogen source.
نویسندگان
چکیده
The uptake of methylamine as the sole nitrogen, but not carbon, source by Pseudomonas sp. strain MA was investigated. Under these growth conditions, a high-affinity, low-capacity uptake system was present having a Km of 16 microM and Vmax of 2 nmol.min-.mg (dry weight) of cells that was competitively inhibited by ammonium chloride. The transport system was induced by growth on succinate with methylamine as the sole nitrogen source.

Transport of methylamine by Pseudomonas sp. MA.
Pseudomonas sp. MA grows on methylamines as a sole source of carbon, nitrogen, and energy. The transport of methylamine into the organism was investigated. It was found that this organism possesses an inducible transport system for methylamine having the following physical parameters: pH optimum, 7.2; temperature optimum, 30 to 35 degrees C; Km, 1 to 30 mM; Vmax, 90 to 120 nmol/min per mg (dry ...
متن کاملUptake of methylamine and methanol by Pseudomonas sp. strain AM1.
The uptake of methylamine and of methanol by the facultative methylotroph Pseudomonas sp. strain AM1 was investigated. It was found that this organism possesses two uptake systems for methylamine. One of these operates when methylamine is the sole source of carbon, nitrogen, and energy. It has a Km of 1.33 X 10(-4) M and a Vmax of 67 nmol/min per mg of cells (dry weight). The other system, foun...
متن کاملProduction of volatile nitrogenous compounds from the degradation of streptomycin by Pseudomonas maltophilia.
Ammonia, methylamine, and pyridine were detected in broth filtrates of a streptomycin-degrading strain of Pseudomonas maltophilia during growth on streptomycin as a sole carbon and nitrogen source. Ammonia and methylamine, quantitatively measured by conversion to chromophores with picryl sulfonic acid, were found to accumulate in broth, whereas pyridine concentration increased in the early stag...
متن کاملMethylamine metabolism in Hansenula polymorpha: an in vivo 13C and 31P nuclear magnetic resonance study.
Methylamine uptake, oxidation, and assimilation were studied in Hansenula polymorpha, a methylotrophic yeast. The constitutive ammonia transport system was shown to be effective at accumulating methylamine within cells cultured with methylamine or ammonia as a nitrogen source. [13C]methylamine oxidation rates were measured in vivo in methylamine-adapted cells by 13C nuclear magnetic resonance a...
متن کاملA strong nitrogen source-regulated promoter for controlled expression of foreign genes in the yeast Pichia pastoris.
In methylotrophic yeasts, glutathione-dependent formaldehyde dehydrogenase (FLD) is a key enzyme required for the metabolism of methanol as a carbon source and certain alkylated amines such as methylamine as nitrogen sources. We describe the isolation and characterization of the FLD1 gene from the yeast Pichia pastoris. The gene contains a single short intron with typical yeast-splicing signals...
