New ways to break an old bond: the bacterial carbon-phosphorus hydrolases and their role in biogeochemical phosphorus cycling.
Phosphonates are organophosphorus molecules that contain the highly stable C-P bond, rather than the more common, and more labile, C-O-P phosphate ester bond. They have ancient origins but theirExpand

Organophosphonates revealed: new insights into the microbial metabolism of ancient molecules
Organophosphonates are ancient molecules that contain the chemically stable C–P bond, which is considered a relic of the reducing atmosphere on primitive earth. Synthetic phosphonates now have a wideExpand

The purification and properties of phosphonoacetate hydrolase, a novel carbon-phosphorus bond-cleavage enzyme from Pseudomonas fluorescens 23F.
A novel, inducible, carbon-phosphorus bond-cleavage enzyme, phosphonoacetate hydrolase, was purified from cells of Pseudomonas fluorescens 23F grown on phosphonoacetate. The native enzyme had aExpand

A nonradioactive method for the assay of polyphosphate kinase activity and its application in the study of polyphosphate metabolism in Burkholderia cepacia.
Studies of polyphosphate (polyP) metabolism in microorganisms have been hampered by the lack of a convenient method for the assay in cell extracts of the activity of polyphosphate kinase (PPK), theExpand
