Assay of carboxypeptidase N activity in serum by liquid-chromatographic determination of hippuric acid.
Clin. Chem. 31(12) , 1936-9, (1985) We describe conditions for determining carboxypeptidase N (EC 3.4.17.3) activity by liquid chromatography. Serum (10 microL) is mixed with the artificial substrates hippuryl-L-arginine (30 mmol/L) and hippuryl-L-lysine (100 mmol/L) in 50 mmol/L 4-(2-hydroxyet... |

Isolation and purification of creatine kinase conversion factor from human serum and its identification as carboxypeptidase N.
Clin. Biochem. 20(1) , 21-9, (1987) Creatine kinase conversion factor has been isolated from human serum and purified to electrophoretic and chromatographic homogeneity. The enzyme sequentially converts creatine kinase MM3 to MM2 and MM1 and hydrolyzes lysine and arginine from hippuryl-L-lysine... |

Model studies on protein glycation: influence of cysteine on the reactivity of arginine and lysine residues toward glyoxal.
Ann. N. Y. Acad. Sci. 1126 , 248-52, (2008) Mixtures of N alpha-hippurylarginin, N alpha-hippuryllysine, and glyoxal were incubated in the absence and presence of N alpha-acetylcysteine in order to assess the individual reactivity of these nucleophilic amino acid residues. The incubations were performe... |

The kininases of Bothrops jararaca plasma.
Acta Physiol. Lat. Am. 30(4) , 269-74, (1980) Evidence is presented to suggest that kininase activity of Bothrops jararaca plasma is due to the presence of at least three distinct enzymes: a carboxypeptidase B type enzyme, similar to that found in human plasma in that its activity is enhanced by Co2+ (1 ... |

Human 'creatine kinase conversion factor' identified as a carboxypeptidase.
Biochem. J. 221(2) , 465-70, (1984) The effect of partially purified 'creatine kinase conversion factor' on rabbit muscle creatine kinase is shown to be that of a carboxypeptidase, removing the C-terminal lysine residue from both subunits. These changes fully explain the three-banded electropho... |

Formation of peptide-bound Heyns compounds.
J. Agric. Food Chem. 56(7) , 2522-7, (2008) The reaction of the Nalpha-hippuryllysine (BzGK) with fructose was investigated in two model systems to obtain an insight in fructose-induced modification of lysine in bakery products. After BzGK and fructose had been heated in a buffered low-moisture model s... |

Chemical basis for the extreme skin sensitization potency of (E)-4-(ethoxymethylene)-2-phenyloxazol-5(4H)-one.
Chem. Res. Toxicol. 23(12) , 1913-20, (2010) (E)-4-(ethoxymethylene)-2-phenyloxazol-5(4H)-one, commonly referred to as oxazolone, is the most potent skin sensitizer in published databases as determined with the murine local lymph node assay. It has been used very widely in immunological research to indu... |

Rapid assay of human plasma carboxypeptidase N by high-performance liquid chromatographic separation of hippuryl-lysine and its product.
J. Chromatogr. A. 266 , 173-7, (1983) A rapid and sensitive method for measuring carboxypeptidase N (CPN) activity in human plasma is described. The procedure is based on the hydrolysis of a high-specificity/low-affinity substrate, hippuryl-L-lysine, to its products hippuric acid and lysine. The ... |

Reaction of N(alpha)-hippuryllysine with 2-hydroxyheptanal: a model for lysine-directed protein modifications by lipid peroxidation.
Chem. Phys. Lipids 124(2) , 81-8, (2003) 2-Hydroxyheptanal (2-HH) is one of the major aldehydes derived from peroxidation of polyunsaturated fatty acids. In the present study, to obtain an insight into the contributions of 2-HH to protein modifications during lipid peroxidation, a lysine-containing ... |

Alterations of carboxypeptidases N activities in patients with thyroid dysfunction.
Clin. Biochem. 20(1) , 43-6, (1987) Serum carboxypeptidases N (EC. 3.4.17.3) were determined spectrophotometrically in 87 patients with disturbances of thyroid function and in 131 euthyroid individuals, including 33 women taking estrogens for contraception. Carboxypeptidases N (CN) can be subdi... |
