    In addition to hepatocytes that express FAH, cells that do not produce FAA due to mutations in enzymes upstream in tyrosine catabolism are also strongly selected. Phosphonate analogues of carboxypeptidase A substrates are potent transition-state analogue inhibitors. Due to the quadruple moment of B, the peaks in the boron and phosphorous NMR spectra were broad and the values of 1 J B ,P obtained from a set of spectra 31 P and 11 B of the same compound were not always identical.
