additional information spectrometric fluorescence quantification of allantoin in biological samples by cap-immobilized allantoinase/resorcinol assay, formation of the lactone of 2,2',4,4'-tetrahydroxy-diphenylacetic acid at 100°C, specific for allantoin, method development and evaluation, overview. Other compounds such as sodium pyruvate, 2-oxoglutaric acid, 2-oxobutyric acid, oxalacetic acid, oxalic acid, formic acid, citric acid,glycolic acid, succinic acid, acetic acid, tartaric acid and salicylic acid do not form the fluorescent species. Also no reactivity with the intermediates of uricolytic pathway, 5-hydroxyisourate and 2-oxo-4-hydroxy-4-carboxy-5-ureidoimidazoline. The assay can be applied to the evaluation of the catalytic activity of PEGylated enzymes conceived for the treatment of hyperuricemia-related conditions Pseudomonas fluorescens ?
