Cytosolic C-P Bond Cleavage Activity in Bacterial Cells Isolated from Soil

概要

論文の詳細を見る
Three kinds ob bacteria(CP1,CP9 and CP10), able to accumulate inorganic phosphate(Pi)in a growth medium containing phosphonoacetate as a sole source of phosphorus, were isolated from two hundred soil samples. C-P bond cleavage activity in these strains was determined using extracts prepared from cells grown on a medium containing phosphonoacetate. The activity was not found in cell extracts of CP1. Cell extracts prepared from CP9 catalyzed the liberation of Pi only from phosphonoacetate and 2-aminoethylphosphonate. The cell size of CP10 was abnormally large compared with that of CP1 and CP9,and the extracts of CP10 catalyzed the cleavage of C-P bonds in methylphosphonate, phosphonoacetate, phenylphosphonate, 2-amino-ethylphosphonate, 2-amino-4-phosphonobutyrate, glyphosate and in phosphonomycine.
