Methylamine uptake in Pseudomonas species strain MA: utilization of methylamine as the sole nitrogen source.
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.
