Alkaloids 182-191 alanine--glyoxylate and serine--pyruvate aminotransferase Homo sapiens 195-199 16867724-3 1984 Concentrations of the individual alkaloids are calculated using two simultaneous equations derived from the experimentally determined coefficients of fluorescence of solutions (1 mug/ml) of emetine and cephaeline at pH 1 and pH 12. Alkaloids 33-42 alanine--glyoxylate and serine--pyruvate aminotransferase Homo sapiens 216-220
