Glyphosate, part of the herbicide "Roundup", is a phosphonate. 2-aminoethylphosphonic acid: the first identified natural phosphonate. Phosphonates are one of the three sources of phosphate intake in biological cells. [citation needed] The other two are inorganic phosphate and organophosphates.
Acting as antagonists of amino acids, they inhibit enzymes involved in amino acid metabolism and thus affect the physiological activity of the cell. These effects may be exerted as antibacterial, plant growth regulatory or neuromodulatory. They can act as ligands, and heavy metal complexes with aminophosphonates have medical applications. [2]
The systematic name of this enzyme class is (2-aminoethyl)phosphonate:pyruvate aminotransferase. Other names in common use include (2-aminoethyl)phosphonate transaminase , (2-aminoethyl)phosphonate aminotransferase , (2-aminoethyl)phosphonic acid aminotransferase , 2-aminoethylphosphonate-pyruvate aminotransferase , 2-aminoethylphosphonate ...
[4] [1] In addition, it is a degradation product of other aminophosphonates, which have applications as antiscalant and water treatment. [5] AMPA was found in the final effluent of some wastewater treatment plants at concentrations of up to 10μg/l. [6] AMPA can be detected after membrane filtration. [7]

The "backbone" of a polyphosphoric acid molecule is a chain of alternating P and O atoms. Each extra orthophosphoric unit that is condensed adds 1 extra H atom, 1 extra P atom, and 3 extra O atoms. The general formula of a polyphosphoric acid is H n+2 P n O 3n+1 or HO[−P(O)(OH)−O−] n H.
The HAAAP family includes three well-characterized aromatic amino acid/H + symport permeases of E. coli and two hydroxy amino acid permeases. The aromatic amino acid/H + symport permeases are: Mtr, a high affinity tryptophan-specific permease (TC# 2.A.42.1.2). TnaB, a low affinity tryptophan permease (TC# 2.A.42.1.3).
